Description

The JRW series provide up to 70A output current in an industry standard half brick, which makes it an ideal choice

for optimum space, high current and low voltage applications. The converter incorporates synchronous rectification

technology and innovative packaging techniques to achieve high efficiency reaching 91% at 3.3V full load. The ultra

high efficiency of this converter leads to lower power dissipation such that for most applications a heat sink is not

required. The output is fully isolated from the input, allowing versatile polarity configurations and grounding

connections. Built-in filtering for both input and output minimizes the need for external filtering.

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 an

integrated part of 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 20A (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

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 43, a

100μF electrolytic capacitor (ESR< 0.7Ω at 100kHz),

mounted close to the power module helps ensure the

stability of the unit. Consult the factory for further

application guidelines.

Output Capacitance

Note: Measure input reflected-ripple current with a simulated source

inductance (LTEST) of 12 µH. Capacitor CS offsets possible battery

impedance. Measure current as shown above.

High output current transient rate of change (high

di/dt) loads may require high values of output

capacitance to supply the instantaneous energy

requirement to the load. To minimize the output

voltage transient drop during this transient, low E.S.R.

(equivalent series resistance) capacitors may be

required, since a high E.S.R. will produce a

correspondingly higher voltage drop during the

current transient.

Figure 43. Input Reflected Ripple Current Test

Setup.

Output capacitance and load impedance interact with

the power module’s output voltage regulation control

system and may produce an ’unstable’ output

condition for the required values of capacitance and

E.S.R.. Minimum and maximum values of output

capacitance and of the capacitor’s associated E.S.R.

may be dictated, depending on the module’s control

system.

The process of determining the acceptable values of

capacitance and E.S.R. is complex and is load-

dependant. Lineage Power provides Web-based tools

to assist the power module end-user in appraising

and adjusting the effect of various load conditions and

output capacitances on specific power modules for

various load conditions.

Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or

tantalum capacitor. 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 44. Output Ripple and Noise Test Setup.

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 Recognized, CSA^†C22.2

No. 60950-3-01 Certified, and EN 60950-1 (VDE^‡

0805): 2001-12 Licensed.

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.

These converters have been evaluated to the spacing

requirements for Basic Insulation per the above safety

standards. For Basic Insulation models (“-B” Suffix),

1500 Vdc is applied from Vi to Vo to 100% of outgoing

production.

Setup.

For end products connected to –48V dc, or –60Vdc

nominal DC MAINS (i.e. central office dc battery

plant), no further fault testing is required.

Safety Considerations (continued)

*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.

For all input sources, other than DC MAINS, where

the input voltage is between 60 and 75V dc

(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.

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 rated 94V-0.

The input to these units is to be provided with a

maximum 20A fast-acting (or time-delay) fuse in the

unearthed lead.

Overtemperature Protection

Feature Descriptions

These modules feature an overtemperature protection

circuit to safeguard against thermal damage. The

Remote On/Off

Two remote on/off options are available. Positive logic

remote on/off 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 turns the module off

during a logic high and on during a logic low. Negative

logic, device code suffix "1," is the factory-preferred

configuration. To turn the power module on and off,

the user must supply a switch to control the voltage

between the on/off terminal and the VI (-) terminal

(Von/off). The switch can be an open collector or

equivalent (see Figure 46). A logic low is Von/off = 0

V to I.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 allowable leakage current of the switch at

Von/off = 15V is 50 µA. If not using the remote on/off

feature, perform one of the following to turn the unit

on:

circuit shuts down and latches off the module when

the maximum device reference temperature is

exceeded. 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.

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.

For negative logic, short ON/OFF pin to VI(-).

For positive logic: leave ON/OFF pin open.

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 terminals must not exceed the

output voltage sense range given in the Feature

Specifications table i.e.:

[Vo(+) – Vo(-)] – [SENSE(+) – SENSE(-)] ≤ 10% of

V_o,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

47. 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 46. 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 seconds. If overcurrent persists for few

seconds, the module will shut down and remain latch-

off. The overcurrent latch is reset by either cycling the

input power or by toggling the on/off pin for one

second. 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.

An auto-restart option is also available.

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.

Voltage.

Output Voltage Programming

Trimming allows the user to increase or decrease the

output voltage set point of a module. This is

accomplished 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.

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.

If not using the trim feature, leave the TRIM pin open.

With an external resistor between the TRIM and

SENSE(-) pins (Radj-down), the output voltage set

point (Vo,adj) decreases (see Figure 36). The

following equation determines the required external-

resistor value to obtain a percentage output voltage

change of Δ%.

Thermal Considerations

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.

Heat-dissipating components are mounted on the

topside of the module. Heat is removed by

conduction, convection and radiation to the

surrounding environment. Proper cooling can be

verified by measuring the thermal reference

temperature (T_ref). The peak temperature (T_ref

)

occurs at the position indicated in Figures 50 - 52.

The temperature at any one of these locations should

not exceed per below table to ensure reliable

operation of the power module.

The output power of the module should not exceed

Ordering Information table.

Although the maximum T_reftemperature of the power

modules is approximately 117 °C, you can limit this

temperature to a lower value for extremely high

reliability.

Heat Transfer via Convection

T_ref1

Increased airflow over the module enhances the heat

transfer via convection. Following derating figures

shows the maximum output current that can be

delivered by each module in the respective orientation

without exceeding the maximum T_reftemperature

versus local ambient temperature (T_A) for natural

convection through 2m/s (400 ft./min).

is needed, please consult with your Lineage Power

representative for more details.

Layout Considerations

The JRW power module series are low profile in order

to be used in fine pitch system and architectures. As

such, component clearances between the bottom of

the power module and the mounting board are limited.

Either avoid placing copper areas on the outer layer

directly underneath the power module or maintain a

minimum clearance through air of 0.028 inches

between any two “opposite polarity” components,

including copper traces under the module to

components on the JRW module..

For modules with a “7” (case (heatplate) pin) and “-H”

(heatplate) option:

To meet Basic Insulation in the end product 1)

between the input and output of the module, or 2)

between the input and the earth ground, a series

capacitor (capable of withstanding 1500V dc) needs

to inserted between the case pin and the end

termination point, if the case pin is connected to the

input or the output of the JRW module or to earth

ground.

For additional layout guide-lines, refer to

FLTR100V10 data sheet.

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 (AP01-056EPS).

Through-Hole Lead-Free Soldering

Information

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 single or dual wave soldering machines. The

pins have an RoHS-compliant 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
