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
an integrated part of complex power architecture. To preserve maximum flexibility, internal fusing is not included.
Always use an input line fuse, to achieve maximum safety and system protection. The safety agencies require a fast-
acting fuse with a maximum rating of 30A (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.

Test Configurations
Note: Measure the input reflected-ripple current with a
simulated source inductance (LTEST) of 12 µH. Capacitor CS
offsets possible battery impedance. Measure the current, as
shown above.
Figure 7. Input Reflected Ripple Current Test Setup.
Note: Use a C
out
(470 µF Low ESR aluminum or tantalum
capacitor typical), a 0.1 µF ceramic capacitor and a 10 µF
ceramic capacitor, and Scope measurement should be made
using a BNC socket. Position the load between 51 mm and 76
mm (2 in. and 3 in.) from the module.
Figure 8. Output Ripple and Noise Test Setup.
Note: All measurements are taken at the module terminals.
When socketing, place Kelvin connections at module terminals
to avoid measurement errors due to socket contact resistance.
Figure 9. Output Voltage and Efficiency Test Setup.
Design Considerations
Input Source Impedance
The power module should be connected to a low
ac-impedance source. Highly inductive source
impedance can affect the stability of the power module.
For the test configuration in Figure 7, a 470μF Low
ESR aluminum capacitor, C
IN
, mounted close to the
power module helps ensure the stability of the unit.
Consult the factory for further application guidelines.
Output Capacitance
The FNW700R power module requires a minimum
output capacitance of 470µF Low ESR aluminum
capacitor, C
out
to ensure stable operation over the full
range of load and line conditions, see Figure 8. If the
ambient temperature is under -20
O
C, it is required to
use at least 3 of the minimum capacitors in parallel. In
general, the process of determining the acceptable
values of output capacitance and ESR is complex and
is load-dependant.
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., UL60950-1, CSA C22.2 No. 60950-1-03,
EN60950-1 and VDE 0805:2001-12.
For end products connected to –48V
dc
, or –60V
dc
nominal DC MAINS (i.e. central office dc battery plant),
no further fault testing is required. *Note: -60V
dc
nominal battery 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 60V
dc
, if the input meets all of
the requirements for SELV, then:
The output may be considered SELV. Output
voltages will remain within SELV limits even with
internally-generated non-SELV voltages. Single
component failure and fault tests were performed
in the power converters.
One pole of the input and one pole of the output
are to be grounded, or both circuits are to be kept
floating, to maintain the output voltage to ground
voltage within ELV or SELV limits. However, SELV
will not be maintained if V
I
(+) and V
O
(+) are
grounded simultaneously.

LINEAGE POWER 7
Safety Considerations (continued)
For all input sources, other than DC MAINS, where the
input voltage is between 60 and 75Vdc (Classified as
TNV-2 in Europe), the following must be meet, if the
converter’s output is to be evaluated for SELV:
The input source is to be provided with reinforced
insulation from any hazardous voltage, including
the ac mains.
One VI pin and one Vo pin are to be reliably
earthed, or both the input and output pins are to be
kept floating.
Another SELV reliability test is conducted on the
whole system, as required by the safety agencies,
on the combination of supply source and the
subject module to verify that under a single fault,
hazardous voltages do not appear at the module’s
output.
All flammable materials used in the manufacturing of
these modules are rated 94V-0, or tested to the
UL60950 A.2 for reduced thickness.
The input to these units is to be provided with a
maximum 30 A fast-acting fuse in the unearthed lead.
Feature Description
Remote On/Off
Remote ON/OFF control is available as standard and
has positive logic remote On/Off mode only. The
converter will be active as long as a current Ion/off (1 to
5mA) is flowing into the ON/OFF+ (pin 4) and from the
ON/OFF- (pin 3), and inactive when no current is
flowing. Remote control pins are isolated up to 1.5 kV.
The voltage to drive this current can be derived from
the input voltage, the output voltage, or an external
supply with an appropriate current limit resistor. The
maximum forward current allowable without damage is
5 mA, and the maximum reverse current is 10mA. A
typical remote ON/OFF circuit is shown as Figure 10.
The current limit resistor (R1) is connected from Vin (+)
pin to ON/OFF + pin, an open collector or an equivalent
switch can be connected between ON/OFF - and VI (-)
pins to control ON/OFF operation. A 0 Ohm resistor
(R2) can be used if no open collector or switch used.
For 48Vin, an appropriate R1 value is recommended to
be 30Kohm (0.5W).
Figure 10. Circuit configuration for using Remote
On/Off Implementation.
Overcurrent Protection
To provide protection in a fault output overload
condition, the module is equipped with internal current-
limiting circuitry and can endure current limit for few
milli-seconds. A latching shutdown option is standard. If
overcurrent persists for few milli-seconds, the module
will shut down and remain off until the module is reset
by either cycling the input power or by toggling the
on/off pin for one second.
An auto-restart option (4) is also available in a case
where an auto recovery is required. If overcurrent
persists for few milli-seconds, the module will shut
down and auto restart until the fault condition is
corrected. If the output overload condition still exists
when the module restarts, it will shut down again. This
operation will continue indefinitely, until the overcurrent
condition is corrected.
Over Voltage Protection
The output overvoltage protection consists of circuitry
that monitors the voltage on the output terminals. If the
voltage on the output terminals exceeds the over
voltage protection threshold, then the module will
shutdown and latch off. The overvoltage latch is reset
by either cycling the input power for one second or by
toggling the on/off signal for one second. The
protection mechanism is such that the unit can continue
in this condition until the fault is cleared.
An auto-restart option (4) is also available in a case
where an auto recovery is required.
Output Voltage Programming
Trimming allows the user to increase or decrease the
output voltage set point of a module. Trimming down is
accomplished by connecting an external resistor
between the TRIM pin and the SENSE(-) pin. Trimming
up is accomplished by connecting external resistor
between the SENSE(+) pin and Vo(+) pin. The trim
resistor should be positioned close to the module.
Be sure to use a zero resistor or short SENSE(+) and
Vo(+) pins when the trim up function is not used.
If not using the trim down feature, leave the TRIM pin
open.

The voltage between the V

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 voltage of the module can be
increased, which the same output 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.

Feature Description (continued)
Remote sense
Remote sense minimizes the effects of distribution
losses by regulating the voltage at the remote-sense
connections (see Figure 13). For No Trim or Trim down
application, the voltage between the remote-sense pins
and the output terminals must not exceed the output
voltage sense range given in the Feature Specifications
table i.e.:
[Vo(+) – Vo(-)] – [SENSE(+) – SENSE(-)] 2% of Vo,nom.
The voltage between the Vo(+) and Vo(-) terminals
must not exceed the minimum output overvoltage shut-
down value indicated 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 13. If not using the
remote-sense feature to regulate the output 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 defined as the voltage at the
output terminals multiplied by the output current. When
using remote sense and trim: the output voltage of the
module can be increased, which at the same output
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 13. Effective Circuit Configuration for Single-
Module Remote-Sense Operation Output Voltage.
Over Temperature Protection
The FNW700R module provides with non-latching over
temperature protection. A temperature sensor monitors
the operating temperature of the converter. If the
reference temperature exceeds a threshold of 106 °C
(typical) at the center of the baseplate, the converter
will shut down and disable the output. When the
baseplate temperature has decreased by
approximately 20 ºC the converter will automatically
restart.
The module can be restarted by cycling the dc input
power for at least one second or by toggling the remote
on/off signal for at least one second.
Auxiliary Power Output
The module has an auxiliary power output, available on
pin 16, referenced to the Sense- pin. The output is
derived from the internal secondary bias supply and is
capable of delivering up to 15 mA, with a voltage range
that varies between 9V
dc
and 13 V
dc
. This supply is
typically used to drive LEDs. To prevent internal
module damage, do not connect or short this pin to any
other pin on the module.
Power Good Signal
The module contains a power good signal on pin 15,
consisting of an open collector circuit that is referenced
to the Sense- pin on the secondary side of the module.
The power good signal is active low, when the module
is operating normally. The maximum current that can
sunk at this pin, during normal operation active low, is
35 mA
dc
, and the maximum voltage allowed on the pin,
during module abnormal operation active high, is 35V
dc
.
During transient load changes or during overcurrent
hiccup events, the sanity of the power good signal is
not guaranteed.

Thermal Considerations
The power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation of the unit.
Heat-dissipating components inside the unit are
thermally coupled to the case. Heat is removed by
conduction, convection, and radiation to the
surrounding environment. Proper cooling can be
verified by measuring the case temperature. Peak
temperature (T
C
) occurs at the position indicated in
Figure 14.
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.
For reliable operation this temperature should not
exceed 100ºC.
Figure 14. Case (T
c
) Temperature Measurement
Location (top view).
The output power of the module should not exceed the
rated power for the module as listed in the ordering
Information table.
Although the maximum T
C
temperature of the power
modules is 100 °C, you can limit this temperature to a
lower value for extremely high reliability.
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.
Thermal Derating
Thermal derating is presented for two different
applications: 1) coupled to a cold plate inside a sealed
clamshell chassis, without any internal air circulation,
and 2) traditional open chassis or cards with force air
flow. In application 1, the module is cooled entirely by
conduction of heat from the module primarily through
the top surface to a coldplate, with some conduction
through the module’s pins to the power layers in the
system board; for application 2; the module is cooled
by heat removal into a forced airflow that passes
through the interior of the module and over the top
baseplate and/or an attached heatsink.

LINEAGE POWER 11
Layout Considerations
The FNW700R power module series are aluminum
base board packaged style, as such; component
clearance between the bottom of the power module
and the mounting (Host) board is limited. Avoid placing
copper areas on the outer layer directly underneath the
power module.
Through-Hole Lead-Free Soldering
Information
The RoHS-compliant, Z version, through-hole products
use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-
compliant components. The non-Z version products
use lead-tin (Pb/Sn) solder and RoHS-compliant
components. Both version modules are designed to be
processed through single or dual wave soldering
machines. The pins have an RoHS-compliant, pure tin
finish that is compatible with both Pb and Pb-free wave
soldering processes. A maximum preheat rate of 3C/s
is suggested. The wave preheat process should be
such that the temperature of the power module board is
kept below 210C. For Pb solder, the recommended
pot temperature is 260C, while the Pb-free solder pot
is 270C max. Not all RoHS-compliant through-hole
products can be processed with paste-through-hole Pb
or Pb-free reflow process. If additional information is
needed, please consult with your Lineage Power
representative for more details.
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 procedures,
refer to Lineage Power Board Mounted Power
Modules: Soldering and Cleaning Application Note.
