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

, 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

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

, or –60V

nominal DC MAINS (i.e. central office dc battery plant),

no further fault testing is required. *Note: -60V

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

, 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

(+) and V

(+) 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

limit includes any increase in voltage due to remote-

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.

LINEAGE POWER 9

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

and 13 V

. 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

, and the maximum voltage allowed on the pin,

during module abnormal operation active high, is 35V

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

) 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

) 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

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.

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 3C/s

is suggested. The wave preheat process should 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

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.
