Description
The HW/HC series power modules are isolated dc-dc converters that operate over a wide input voltage range of 18
to 36 Vdc (HC) or 36 to 75 Vdc (HW) and provide one precisely regulated output. The output is fully isolated from
the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency,
e.g. typical efficiency of 87% 3.3V/5A, 86% at 2.5V/6A. Built-in filtering for both input and output minimizes the need
for external filtering. These open frame modules are available either in surface-mount (-S) or in through-hole form.
RoHS Compliant

Absolute Maxim um Ratings
Stresses in exces s of the abso lute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect the device reliability.

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 applications, ranging from simple standalone operation to being
part of complex 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 fast-
acting fuse with a maximum rating of 3A (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.

Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance source. A highly inductive source
impedance can affect the stability of the power module.
For the test configuration in Figure 61, a 33μF
electrolytic capacitor (ESR<0.7Ω at 100kHz), mounte d
close to the power module helps ensure the stability of
the unit. Consult the factory for further application
guidelines.
Safety Considerations
For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standard,
i.e., UL 60950-1-3, CSA C22.2 No. 60950-00, and VDE
0805:2001-12 (IEC60950-1).
If the input source is non-SELV (ELV or a hazardous
voltage greater than 60 Vdc and less than or equal to
75Vdc), for the module’s output to be considered as
meeting the requirements for safety extra-low voltage
(SELV), all of the following must be true:
The input source is to be provided with reinforced
insulat i on from any other hazardous voltages, including
the ac mains.
One VIN pin and one VOUT pin are to be grounded, or both
the input and output pins are to be kept floating.
The input pins of the module are not operator accessible.
Another SELV reliabi l ity test is conducted on the whole
system (com bi nation of supply s ource and subject
module), as required by the safety agencies, to verify that
under a single fault, hazardous voltages do not appear at
the module’s output.
Note: Do not ground either of the input pins of the
module without grounding one of the output pins.
This may allow a non-SELV voltage to appear
between the output pins and ground.
The power module has extra-low voltage (ELV) outputs
when all inputs are ELV.
For input voltages exceeding –60 Vdc but less than or
equal to –75 Vdc, these converters have been evaluated
to the applicable requirements of BASIC INSULATION
between secondary DC MAINS DISTRIBUTION input
(classified as TNV -2 i n Europe) and unearthed SELV
outputs.
"All flammable materials used in the manufacturing of
these modul es are ra ted 94V-0 and UL60950 A.2 for
reduced thicknesses.
The input to these units is to be provided with a
maximum 3A fast-acting fuse in the unearthed lead."

Feature Description
Remote On/Off
Two remote on/off options are available. Positive logic
turns the module on during a logic high voltage on the
ON/OFF pin, and off during a logic low. Negative logic
remote On/Off, device code suffix “1”, turns the module
off during a logic high and on during a logic low.
To maintain compat ibi lity w ith LW series power modules
the Remote On/Off pin is optional for the TH (through
hole) version. Standard TH modules have no On/Off pin
fitted. TH modules ordered with device code suffix “1”
are negative logic with the On/Off pin fitted.

Figure 64. Remote On/Off Implementation.
To turn the power module on and off, the user must
supply a switch (open collector or equivalent) to control
the voltage (Von/off) between the ON/OFF terminal and
the VIN(-) terminal. Logic low is 0V ≤ Von/off ≤ 1.2V. The
maximum Ion/off duri ng a logic low is 1mA, the switch
should be maintain a logic low level whilst sinking this
current.
During a logic high, the typical Von/off generated by the
module is 5.8V, and the maximum allowable leakage
current at Von/off = 5.8V is 10μA.
If not using the remote on/off feature:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to VIN(-).
Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with interna l
current-limiting circuitr y and ca n endure current limiting
continuously. At the point of current-limit inceptio n, the
unit enters hiccup mod e. The unit opera tes normally
once the output current is brought back into its specified
range. The average output current during hiccup is 10%
IO, max.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module will
only begin to operate once the input voltage is raised
above the undervoltage lockout turn-on threshold,
VUV/ON.
Once operating, the module will continue to operate until
the input voltage is taken below the undervoltage turn-off
threshold, VUV/OFF.
Over Volta g e Protection
The output overvoltage protection consists of circuitry
that internally clamps the output voltage. If a more
accurate outp ut overv olt age protection sche me is
required then this should be implemented externally via
use of the remote on/off pin.
Over Temperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 125 oC is
exceeded at the ther mal reference point Tref . Once the
unit goes into thermal shutdown it will then wait to cool
before attempt ing to re start .
Output Voltage Programming
Trimming allows the output voltage set point to be
increased or decreased, this is accomplished by
connecting an external resistor between the TRIM pin
and either the VO(+) pin or the VO(-) pin (COM pin) .

Thermal Cons i dera tions
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of the
module will result in an increase in reliability. The
thermal data presented here is based on physical
measurements taken in a wind tunnel.
The thermal reference point, Tref used in the
specifications is shown in Figure 66. For reliable
operation this temperature should not exceed 115 oC.
Figure 66. Tref Temperature Measurement Location.
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-
Mounted Power Modules” for a detailed discussion of
thermal aspects including maximum device
temperatures.
Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Derating figures showing the
maximum output current that can be delivered by each
module versus local ambient temperature (TA) for natural
convection and up to 3m/s (600 ft./min) are shown in the

For further information on designing for EMC
compliance, please refer to the FLTR100V10 data sheet

Layout Considerations
The HW/HC005 power module series are low profile in
order to be used in fine pitch system card architectures.
As such, component clearance between the bottom of
the power module and the mounting board is limited.
Avoid placing copper areas on the outer layer directly
underneath the power module. Also avoid placing via
interconnects underneath the power module.
For additional layout guide-lines, refer to FLTR100V10

Information
The RoHS-compliant through-hole product s use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-complia nt 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 should be such that the
temperatur e of the pow er module board is kep t below

Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, they have a
relatively large mass when compared with
conventional SMT components. Variables such as
nozzle size, tip sty le, va cuu m pres sure and pla cement
speed should be considered to optimize this process.
The minimum recommended nozzle diameter for
reliable operation is 6mm. The maximum nozzle outer
diameter, which will safely fit within the allowable
component spa cin g, is 9 mm.
Oblong or oval nozzles up to 11 x 9 mm may also be
used within the space available.

Lineage Power Technical Sales Representative.
Reflow Soldering Information
The HW005 family of power modules is available for
either 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 components. It is
recommended that the customer review data sheets
in order to customize the solder reflow profile for each
application board assembly.
The following instructions must be observed when
SMT soldering these unit s. Failure to observ e t he se
instructions may result in the failure of or cause
damage to the modules, and can adversely affect
long-term reliability.
The surface mountable modules in the HW005 family
use our newest SMT technology called “Column Pin”
(CP) connectors. Fig 71 shows the new CP connector
before and after reflow soldering onto the end-board
assembly.
Figure 71. Column Pin Connector Before and After
Reflow Soldering.
The CP is constructed from a solid copper pin with an
integral solder ball attached, which is composed of
tin/lead (Sn/Pb) solder. The CP connector design is
able to compensate for large amounts of co-planarity
and still ensure a reliable SMT solder joint.
Typically , the eutecti c sol der melt s at 183 oC, wets the
land, and subsequently wicks the device connection.
Sufficient time mus t be allow ed to fuse the plat ing on
the connection to ensure a reliable solder join t . There
are several types of SMT reflow technologies
currently used in the industry. These surface mount
power modules can be reliably soldered using natural
forced convection, IR (radiant infrared), or a
combinatio n of conve ctio n/IR . For reliab le sol derin g
the solder reflow profile should be established by
accurately measuring the modules CP connector
temperatures.

Lead Free Solder ing
The –Z version SMT modules of the HW/HC 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 recommended
forced-air-convection reflow profile based on the
volume and thickn es s of the package (t abl e 4-2). The
suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow profile using
Sn/Ag/Cu solder is shown in Figure. 74.
MSL Rating
The HW/HC series SMT modules have a MSL rating
of 2A.
Storage and Hand ling
The recommended storage environment and handling
procedures for moisture-s en sit iv e surf ace mount
packages is detai led in J-STD-033 Rev. A (Handling,
Packing, Shipping 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 packages
should not be broken until time of use. Once the
original 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 humidi t y .
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 appr opri ate sol de r ing, cle ani ng and
drying procedures, refer to Lineage Power Board
Mounted Power Modules: Soldering and Cleaning

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 requirements 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).
