Description

The JW060 Triple-Output-Series Power Modules are dc-dc converters that operate over an input voltage range of

36 Vdc to 75 Vdc and provide three dc outputs. The outputs are fully isolated from the inputs, allowing versatile

grounding connections. Built-in shielding provides improved EMI performance. The modules have a maximum

power rating of 60 W at a typical full-load efficiency of 86%.

The total output power of the JW060 Triple-Output-Series Power Modules is limited to 60 W. The main output

(VO1) is tightly regulated and designed to deliver up to 45 W. The auxiliary outputs (VO2 and VO3) are

cross-regulated and can provide a total of 58 W with the main output loaded at its minimum of 2 W.

The modules have a metal baseplate for excellent thermal performance in a small package. Threaded-through

holes are provided to allow easy mounting or addition of a heat sink for high-temperature applications. The stan-

dard feature set includes output trim and remote on/off for convenient flexibility in distributed power applications.

The JW060 Triple-Output-Series Power Modules use

advanced, surface-mount technology and deliver high-quality,

efficient, and compact dc-dc conversion.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute 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 device reliability.

Fusing Considerations

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 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 normal-blow, dc fuse with a maximum rating of 20 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 for further information.

Cleanliness Requirements

The open frame (no case or potting) power module will meet requirements per J-STD-001B. These requirements

state that solder balls must be attached and their size should not compromise minimum electrical spacing of the

power module.

The cleanliness designator of the open frame power module is C00 (per J specification).

Solder, Cleaning, and Drying Considerations

Post solder cleaning is usually the final circuit-board assembly process prior to electrical testing. The result of inad-

equate circuit-board 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

the Board-Mounted Power Modules Soldering and Cleaning Application Note (AP97-021EPS).

8-203 (C).l

Note: Input reﬂected-ripple current is measured with a simulated

source inductance (LTEST) of 12 µH. Capacitor CS offsets pos-

sible battery impedance. Current is measured at the input of

the module.

Figure 13. Input Reﬂected-Ripple Test Setup

Note: Use the speciﬁed tantalum (larger value) and ceramic capaci-

tors across each output. Scope measurement should be

made by using a BNC socket. Position the load between

51 mm and 76 mm (2 in. and 3 in.) from the module.

Design Considerations

Input Source Impedance

The power module should be connected to a low

ac-impedance input source. Highly inductive source

impedances can affect the stability of the power mod-

ule. For the test conﬁguration in Figure 13, a 33 µF

electrolytic capacitor (ESR < 0.7 Ω at 100 kHz)

mounted close to the power module helps ensure sta-

bility of the unit. For other highly inductive source

impedances, consult the factory for further application

guidelines.

JW060 Triple-Output-Series Power Modules: dc-dc Converters:

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.,

1950,

CSA

C22.2 No. 950-95, and VDE 0805

(EN60950, IEC950).

If the input source is non-SELV (ELV or a hazardous

voltage greater than 60 Vdc and less than or equal to

75 Vdc), for the module’ s output to be considered meet-

ing the requirements of safety extra-low voltage

(SELV), all of the following must be true:

■

The input source is to be provided with reinforced

insulation from any hazardous v oltages, including the

ac mains.

■

One V

pin and one V

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 acces-

sible.

■

Another SELV reliability test is conducted on the

whole system, as required by the saf ety 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.

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 pin and ground.

The power module has extra-low v oltage (ELV) outputs

when all inputs are ELV.

The input to these units is to be provided with a maxi-

mum 20 A normal-blow fuse in the ungrounded lead.

Assembly Considerations

The power module is not encapsulated. It is designed

to be mounted to the printed-wiring board (PWB) after

the assembly cleaning process.

Feature Descriptions

Overcurrent Protection

To provide protection in a fault (output overload) condi-

tion, the unit is equipped with internal current-limiting

circuitry and can endure current limiting for an unlim-

ited duration. At the point of current-limit inception, the

unit shifts from voltage control to current control. If the

output voltage is pulled very low during a severe fault,

the current-limit circuit exhibits foldback char acteristics

(output current decrease). The unit operates normally

once the overload condition is removed.

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 dur-

ing a logic high and on during a logic low.

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 V

(–) terminal (V

on/off

). The

switch can be an open collector or equivalent (see

Figure 16). A logic low is V

on/off

= 0 V to 1.2 V. The

maximum I

on/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 V

on/off

generated by

the power module is 15 V. The maximum allowable

leakage current of the switch is 50 µA. It is not recom-

mended to drive the ON/OFF pin with an external

source; however, if one is used, current into the pin

must not exceed 1 mA.

If not using the remote on/off f eature , do one of the

following:

■

F or negativ e logic , short ON/OFF pin to V

(–).

■

For positive logic, leave ON/OFF pin open.

Output Voltage Set-Point Adjustment

(Trim)

Output voltage trim allows the user to increase or

decrease the output voltage set points of all outputs

simultaneously. This is accomplished by connecting an

external resistor between the TRIM pin and either the

VO1(+) or COM pins. The trim resistor should be posi-

tioned close to the module.

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

With an external resistor between the TRIM and COM

pins (Radj-down), the output voltage set points decrease

(see Figure 17). The following equation, plotted in

Figure 18, gives the required external-resistor value to

lower the output voltages by a percentage (∆%).

With an external resistor connected between the TRIM

and V O1(+) pins (Radj-up), the output voltage set points

increase (see Figure 19).

The following equation, plotted in Figure 20, gives the

required external-resistor value to raise the output volt-

ages by a percentage (∆%).

The voltage between the VO1(+) and COM terminals

must not exceed the minimum output overvoltage shut-

down v oltage as indicated in the F eature Speciﬁcations

table .

The amount of power delivered by the module is

deﬁned as the voltage at the output terminals multiplied

by the output current. When using trim the output volt-

age 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 maxi-

mum output power of the module remains at or below

the maximum rated power.

Voltage

Output Overvoltage Protection

The output overvoltage clamp consists of circuitry that

monitors the voltage on the output terminals. If the volt-

age on the output terminals exceeds the overvoltage

protection threshold, then the module will shut down

and attempt to restart periodically.

Overtemperature Protection

To provide protection in a fault condition, the unit is

equipped with a temperature limiting circuit. This circuit

will not engage unless the unit is operated above the

absolute maximum temperature limit. When active, the

overtemperature circuit lowers all output voltages sufﬁ-

ciently to prevent exceeding the overtemperature

threshold. Recovery from the temperature limit is auto-

matic after the unit cools below the overtemperature

threshold.

Thermal Considerations

Introduction

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 ther-

mally coupled to the metal baseplate. Heat is removed

by conduction, convection, and radiation to the sur-

rounding environment. Proper cooling can be veriﬁed

by measuring the metal baseplate temperature. Peak

temperature (T

) occurs at the position indicated in

Figure 21.

8-716 (C).g

Note: Top view, pin locations are for reference only.

Measurements shown in millimeters and (inches).

Figure 21. Case Temperature Measurement

Location

The temperature at this location should not exceed

100 °C. 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 case temperature of the power

modules is 100 °C, you can limit this temperature to a

lower value for extremely high reliability.

Thermal performance of the module varies with the

direction of airﬂow, assumed to be parallel to one edge

of the baseplate. The best orientation has air entering

the side with input pins, and the second best orienta-

tion has air entering the side closest to the ON/OFF

and V

(–) pins.

Thermal Considerations

(continued)

Introduction

(continued)

Total pow er dissipation for the modules at 48 V input is

given by Figure 24 and Figure 25. Power dissipation at

36 V input is approximately 0.3 W higher than shown

for 48 V input, and power dissipation at 75 V input is

approximately 0.6 W higher than shown for 48 V input.

Heat Transfer Without Heat Sinks

Increasing airﬂow over the module enhances the heat

transfer via convection. Figure 22 shows the maximum

power that can be dissipated by the module without

e xceeding the maximum baseplate temperature v ersus

local ambient temperature (T

), for natural convection

through 4 m/s (800 ft./min.) in transverse (better) orien-

tation, where the air ﬂows parallel to the shorter side.

Note that the natural convection condition was mea-

sured at 0.05 m/s to 0.1 m/s (10 ft./min. to 20 ft./min.);

however, systems in which these power modules may

be used typically generate natural convection airﬂow

rates of 0.3 m/s (60 ft./min.) due to other heat dissipat-

ing components in the system. The use of Figure 22

and Figure 23 is shown in the following example.

Example

What is the minimum airﬂow necessary for a

JW060ABK operating at nominal line, an output current

of 9 A on 5 V, 1.25 A on +12 V, and 0 A on –12 V, and a

maximum ambient temperature of 50 °C?

Solution

@ –12 V = 0 A

Heat Transfer with Heat Sinks

The power modules have through-threaded, M3 x 0.5

mounting holes, which enab le heat sinks or cold plates

to attach to the module. The mounting torque must not

exceed 0.56 N-m (5 in.-lb.). For a screw attachment

from the pin side, the recommended hole size on the

customer’s PWB around the mounting holes is

0.130 ± 0.005 inches. If a larger hole is used, the

mounting torque from the pin side must not exceed

0.25 N-m (2.2 in.-lb.).

Thermal derating with heat sinks is expressed b y using

the ov er all thermal resistance of the module. Total mod-

ule thermal resistance (

ca) is deﬁned as the maximum

case temperature rise (

∆

C, max

) divided by the module

power dissipation (P

The location to measure case temperature (T

) is

shown in Figure 21. Case-to-ambient thermal resis-

tance vs. airﬂow is shown, for various heat sink conﬁg-

urations and heights, in Figure 26. These curves were

obtained by experimental testing of heat sinks, which

are offered in the product catalog.

8-1511 (C)

Figure 26. Case-to-Ambient Thermal Resistance

Curves; Either Orientation

These measured resistances are from heat transfer

from the sides and bottom of the module as well as the

top side with the attached heat sink; therefore, the

case-to-ambient thermal resistances shown are gener-

ally lower than the resistance of the heat sink by itself.

The module used to collect the data in Figure 26 had a

thermal-conductive dry pad between the case and the

heat sink to minimize contact resistance. The use of

Heat Transfer with Heat Sinks

Example

If an 85 °C case temperature is desired, what is the

minimum airﬂow necessary? Assume the JW060ABK

module is operating at nominal line and an output cur-

rent of 9 A on 5 V, 1.25 A on +12 V, and 0 A on –12 V,

maximum ambient air temperature of 40 °C, and a heat

sink that is 0.25 inches.

Solution

Given: V

= 54 V

@ 5 V = 9 A

@ +12 V = 1.25 A

@ –12 V = 0 A

= 40 °C

= 85 °C

Heat sink = 0.25 inch

Determine P

by using Figure 24:

= 11.5 W

Then solve the following equation:

Use Figure 26 to determine air velocity f or the 0.25 inch

heat sink.

The minimum airﬂow necessary for the JW060ABK

module is 0.6 m/s (110 ft./min.).

Custom Heat Sinks

A more detailed model can be used to determine the

required thermal resistance of a heat sink to provide

necessary cooling. The total module resistance can be

separated into a resistance from case-to-sink (

cs) and

sink-to-ambient (

sa) shown below (Figure 27).

8-1304 (C)

Figure 27. Resistance from Case-to-Sink and

Sink-to-Ambient

For a managed interface using thermal grease or foils,

a value of

cs = 0.1 °C/W to 0.3 °C/W is typical. The

solution for heat sink resistance is:

This equation assumes that all dissipated power must

be shed by the heat sink. Depending on the user-

deﬁned application environment, a more accurate

model, including heat transfer from the sides and bot-

tom of the module, can be used. This equation provides

a conservative estimate for such instances.

EMC Considerations

For assistance with designing for EMC compliance,

please refer to the FLTR100V10 data sheet

(DS98-152EPS).

Layout Considerations

Copper paths must not be routed beneath the power

module mounting inserts, which are conductive and

connected together electrically. Furthermore, it is not

recommended that any copper paths be routed under-

neath or near the power module because they are

likely to pick up noise from the module.

F or impro v ed EMI performance, f ollow the layout guide-

lines given in the ﬁlter module FLTR100V10 or

FLTR100V20 data sheets (DS98-152EPS or

DS98-153EPS). For best EMI performance, use either

of these ﬁlter modules at the input of one or more

power modules.
