Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Th ese are absolute stress
ratings only, functional operation of the device is not implie d at these or any other conditions in exce ss of those given in the
operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the
device reliabiltiy.
Electrical Specifications
Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of application s , ranging from simple stand-alone operation to an integrated
part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included however, to achieve
maximum safety and system protection, always use an input line fuse. The safety agencies require a time-delay fuse with a
maximum rating of 5 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush
energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s
data sheet for further information.

Safety Considerations
For safety-agency approval of the system in which the power
module is used, the power module must be installed in com-
pliance with the spacing and separation requirements of the
end-use safety agency standard, i.e., UL60950, CSA C22.2
No. 60950-00, and
VDE 0805:2001-12 (IEC60950, 3rd Ed).
These converters have been evaluated to the spacing
requirements for Basic Insulation, per the above safety stan-
dards.
For Basic Insulation models ("–B" Suffix), 1500 Vdc is
applied from VI to VO to 100% of outgoing production.
For end products connected to –48 Vdc, or –60 Vdc nomianl
DC MAINS (i.e. central office dc battery plant), no further
fault testing is required.
Note:–60 V dc nominal bettery plants are not available in the
U.S. or Canada.
For all input voltages, other than DC MAINS, where the input
voltage is less than 60 Vdc, if the input meets all of the
requirements for SELV, then:
n
The output may be considered SELV. Output voltages will
remain withing SELV limits even with internally-generated
non-SELV voltages. Single component failure and fault
tests were performed in the power converters.
n
One pole of the input and one pole of the output are to be
grounded, or both circuits are to be kept floating, to main-
tain the output voltage to ground voltage within ELV or
SELV limits.
For all input sources, other than DC MAINS, where the input
voltage is between 60 and 75 Vdc (Classified as TNV-2 in
Europe), the following must be adhered to, if the converter’s
output is to be evaluated for SELV:
n
The input source is to be provided with reinforced insula-
tion from any hazardous voltage, including the AC mains.
n
One VI pin and one VO pin are to be reliably earthed, or
both the input and output pins are to be kept floati ng.
n
Another SELV reliability test is conducted on the whole
system, as required by the safety agencies, on the combi-
nation of supply source and the subjec t module to verify
that under a single fault, hazardous voltages do not
appear at the module’s output.
The power module has ELV (extra-low voltage) outputs
when all inputs are ELV.
All flammable materials used in the manufacturing of these
modules are rate d 94V-0, and UL60950A.2 for reduced
thicknesses. The input to these units is to be provided with a
maximum 5A time-delay in the unearthed lead.

Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Highly inductive source imped-
ances can affect the st ability of the power module. If the input
source inductance exceeds 4 µH, a 33 µF electrolytic capaci-
tor (ESR < 0.7 W at 100 kHz) mounted close to the power
module helps ensure stability of the unit.
Feature Descriptions
Remote On/Off
Two remote On/Off options are available. Positive logic
remote On/Off turns the module on during a logic-high volt-
age on the remote ON/OFF pin, and off during a logic low.
Negative logic remote On/Off, device code suffix "1", turns
the module off during logic-high voltage and on during a logic
low.
To turn the power module on and off, the user must supply a
switch to contro l th e vo ltage between the
ON/OFF pin and the VI(–) terminal. The switch may be an
open collector or equivale nt (see Figu re 40). A logic low is
Von/off = –0.7 V to 1.2 V. The maximum Ion/off during a logic
low is 1 mA. The switch should maintain a logic-low voltage
while sinking 1 mA. During a logic high, the maximum Von/off
generated by the power module is 15 V. The maximum allow-
able leakage current of the switch at Von/off = 15 V is 50 µA.
If not using the remote on/off feature, do one of the following:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to VI(–).
Figure 40. Remote On/Off Implementation.
Remote Sense
Remote sense minimizes the effects of distribution losses by
regulating the voltage at the remote sense connections. The
voltage between the remote sense pins and the output termi-
nals must not exceed the output voltage sense range given in
the Feature Specifications table:
[VO(+) – VO(–)] – [SENSE(+) – SENSE(–)] £ 0.5 V
The voltage between the VO(+) and VO(–) terminals must not
exceed the minimum output overvoltage protection value
shown in the Feature Specifications table. This limit includes
any increase in voltage due to remote sense compensation
and output voltage set-point adjustment (trim) (See Figure
41). If not using the remote sense feature to regulate the out-
put at the point of load, then connect SENSE(+) to VO(+) and
SENSE
(–) to VO(–) at the module.
Although the output voltage can be increased by both the
remote sense and by the trim, the maximum increase for the
output voltage is not the sum of both. The maximum increase
is the larger of either the remote sense or the trim.
The amount of power delivered by the module is define d as
the voltage at the output terminals multiplied by the output
current. When using remote sense and trim, the output volt-
age of the module can be increased, which at the same out-
put current would increase the power output of the module.
Care should be taken to ensure that the maximum output
power of the module remains at or below the maximum rated
power.
Figure 41. Effective Equivalent Circuit Configuration for
Single-Mod ule Remote-Sen se Operation.
Output Voltage Set-Point Adjustment (Trim)
Output voltage trim allows the user to increase or decrease
the output voltage set point of a module. This is accom-
plished by connecting an external resistor between the TRIM
pin and either the SENSE(+) or SENSE(–) pins. The trim
resistor should be positioned close to the module. If not using
the trim feature, leave the TRIM pin open.
with an external resistor Rtrim-down between the TRIM and
SENSE(–) pins, the output voltage set point VO, set
decreases (see Figure 48). The following equation deter-
mines the required external-resistor value to trim-down the
output voltage:
Rtrim-down is the external resistor in kΩ
∆% is the percentage change in voltage

Output Voltage Set-Point Adjustment (Trim) (con-
tinued)
Table 1
For example, to trim-down the output voltage of 2.5 V mod-
ule (QW020A0G) by 8% to 2.3 V, Rtrim-down is calculated
as follows:
F= 0.08, A = 5.11, & B = 45.31
Figure 42. Circuit Configuration to Decrease Output
Voltage.
The QW010/015/020 modules have a fixed current-limit set
point. As the output voltage is trim-down, the available out-
put power is reduced.
With an external resistor Rtrim-up, connected between the
TRIM and SENSE(+) pins, the output voltage set point VO,
set increases (see Figure 42). The followi ng equation deter-
mines the required external-resistor value to trim-up and out-
put voltage:
Rtrim-up is the external resistor in kW
∆% is the percentage change in voltage
A and B values are defined in Table 2 for various
models
Table 2
For example, to trim-up the output vo ltage of 1.5 V module
(QW020A0M) by 8% to 1.62 V, Rtrim-up is calculated as fol-
lows:
F= 0.08, A = 3.946, & B = 11.454
Figure 43. Circuit Configuration to Increase Output
Voltage.
The voltage between the VO(+) and VO(–) terminals must
not exceed the minimum output overvoltage protection value
shown in the Feature S pecifications table. This limit includes
any increase in voltage due to remote-sense compensation
and output voltage set-point adjustment trim.
Although the output voltage can be increased by both the
remote sense and by the trim, the maximum increase for the
output voltage is not the sum of both. The maximum
increase is the larger of either the remote sense or the trim.
The amount of power delivered by the module is defined as
the voltage at the output terminals multiplied by the output
current. When using remote sense and trim, the output volt-
age of the module can be increased, which at the same out-
put current would increase the power output of the module.
Care should be taken to ensure that the maximum output
power of the module rema ins at or below the maxi mum
rated power.

Feature Descriptions (continued)
Overcurrent Protection
To provide protection in an output overload faul t condition,
the module is equipped with internal current-limiting circuitry,
and can endure current limiting for an unlimited duration. At
the instance of current-limit inception, the module enters a
"hiccup" mode of operation, whereby it shuts down and auto-
matically attempts to restart. While the fault condition exists,
the module will remain in this mode until the fault is cleared.
The unit operates normally once the output current is
reduced back into its specified range.
Output Overvoltage Protection
The output overvoltage protection consists of circuitry that
monitors the voltage of the output terminals. If the output volt-
age exceeds the overvoltage protection threshold, the mod-
ule enters a "hiccup" mode of operation, whereby it shuts
down and automatically attempts to restart. While the fault
condition exists, the module will remain in this hiccup mode
until the overvoltage fault is cleared.
Overtemperatu re Protection
The output overvoltage protection consists of circuitry that
monitors the voltage on the output terminals. If the output
voltag e exce ed s th e overvoltag e p r ot ection threshol d, the
module enters a "hiccup" mode of operation, whereby it shuts
down and automatically attempts to restart. While the fault
condition exists, the module will remain in this hiccup mode
until the overvoltage fault is cleared.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.

QW010/015/020 Series Power Modules: dc-dc Converters;
Thermal Considerations
The power modules operate in a variety of thermal environ-
ments; however, sufficient cooling should be provided to help
ensure reliable operation of the unit. Heat is removed by con-
duction, convection, and radiation to the surrounding environ-
ment. Proper cooling can be verified by measuring drain pin
of Q560 or of Q10 at the positi on indicated in Figure 44.
The temperature at Q560 and Q10 drain pins should not
exceed 110 °C. The output power of the module should not
exceed the rated power for the module
(VO, set x IO, max).
Although the maximum operating ambient temperature of the
power modules is 85 °C, you can limit this temperature to a
lower value for extremely high reliability.
Figure 44. Temperature Measurem ent
Location,QW015A0F (Top View).
Heat Trans fe r vi a Co nve ct io n
Increasing airflow over the module enhances the heat trans-
fer via convection. Figures 45—55 show the maximum cur-
rent that can be delivered by various modules versus local
ambient temperature (TA) for natural convection through 2 m/
s (400 ft./min.).
Systems in which these power modules may be used typi-
cally generate natural convection airflow rates of 0.3 ms–1
(60 ft./min.) due to other heat-dissipating components in the
system. Therefore, the natural convection condition repre-
sents airflow rates of up to 0.3 ms–1 (60 ft./min.).
Example
What is the minimum airflow necessary for a QW015A0F1
operating at VIN = 48 V, an out put current of 12 A, and a
maximum ambient temperature of 75 °C.
Solution
Given: VIN = 48V
IO = 12 A
TA = 75 °C

Through-Hole Lead-Free Soldering Infor-
mation
The RoHS-compliant through-hole products use the SAC
(Sn/Ag/Cu) Pb-free solder and RoHS-compliant components.
They are designed to be processed through sin gle or dual
wave soldering machines. The pins have an RoHS-compli-
ant finish that is compatible with both Pb and Pb-free wave
soldering processes. A maximum preheat rate of 3°C/s is
suggested. The wave preheat process sh ould be such that
the temperature of the power module board is kept below
210°C. For Pb solder, the recommended pot temperature is
260°C, while the Pb-free solder pot is 270°C max. Not all
RoHS-compliant through-hole pr oducts can be processed
with paste-through-hole Pb or Pb-free reflow process. If addi-
tional information is needed, please consult with your Tyco
Electronics Power System representative for more details.
Surface Mount Information
Pick and Place Area
Although the module weigh t is minimized by using open-
frame construction, the modules have a relatively large mass
compared to conventional surface-mount components. To
optimize the pick-and-place process, automated vacuum
equipment variables such as nozzle size, tip style, vacuum
pressure, and placement speed should be considered. Sur-
face-mount versions of this family have a flat surface which
serves as a pick-and-place location fo r automated vacuum
equipment. The module’s pick-and-place location is identified
in Figure 56.
Figure 50. Pick and Place Location.
Reflow Soldering Information
The QW series of power modules is available for eith er
Through-Hole (TH) or Surface Mount (SMT) soldering.
These power modules are large mass, low thermal resistance
devices and typically heat up slower than other SMT compo-
nents. It is recommended that the customer review data
sheets in order to customize the solder reflow profile for each
application boa rd assembly.
The following instructions must be observed when SMT sol-
dering these units. Failure to observe these instructions may
result in the failure of or cause damage to the modules, and
can adversely affect long-term reliability.
Typically, the eutectic solder melts at 183oC, wets the land,
and subsequently wicks the device connection. Sufficient
time must be allowed to fuse the plating on the connection to
ensure a reliable solder joint. There are severa l types of
SMT reflow technologies currently used in the industry.
These surface mount power modules can be reliably sol-
dered using natural forced convection, IR (radian t infrared),
or a combination of convection/IR.
Figure 51. Recommen de d Re fl ow profile.
Figure 52. Time Limit curve above 2050C.
Lead Free Soldering
The -Z version SMT modules of the QW series are lead-free
(Pb-free) and RoHS compliant and are compatible in a Pb-
free soldering process. Failure to observe the instructions
below may result in the failure of or cause damage to the
modules and can adversely affect long-term reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C (Moisture/
Reflow Sensitivity Classification for Nonhermetic Solid State
Surface Mount Devices) for both Pb-free solder profiles and
MSL classification procedures. This standard provides a rec-
ommended forced-air-convection reflow profile based on the
volume and thickness of the package (table 4-2). The sug-
gested Pb-free solder paste is Sn/Ag/Cu (SAC). The recom-
mended linear reflow profile using Sn/Ag/Cu solder is shown
in Figure. 59.

and Use of Moisture/Reflow Sensitive Surface Mount
Devices). Moisture barrier bags (MBB) with desiccant are
required for MSL ratings of 2 or greater. These sealed pack-
ages should not be broken until time of use. Once the origi-
nal package is broken, the floor life of the product at
conditions of £ 30°C and 60% relative humidity varies
according to the MSL rating (see J-STD-033A). The shelf life
for dry packed SMT packages will be a minimum of 12
months from the bag seal date, when stored at the following
conditions: < 40° C, < 90% relative humidity.
Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The result
of inadequate cleaning and drying can affect both the
reliability of a power module and the testability of the finished
circuit-board assembly. For guidance on appropriate
soldering, cleaning and drying proce dures, refer to Tyco
Electronics Board Mounted Power Modules: Sold ering and
Cleaning Application Note (AP01-056EPS).

Ag/Cu solder.
Solder Ball and Cleanliness Requirements
The open frame (no case or potting) power module will meet
the solder ball requirements per J-STD-001B. These require-
ments state that solder balls must neither be loose nor violate
the power module minimum electrical spacing.
The cleanliness designator of the open frame power module
is C00 (per J specification).
