Description

The EQW series, Eighth-brick power modules are isolated dc-dc converters that can deliver up to 25A of output

current and provide a precisely regulated output voltage over a wide range of input voltages (Vi = 36 -75Vdc). The

modules achieve full load efficiency of 88% at 3.3V output voltage. The open frame modules construction, available

in both surface-mount and through-hole packaging, enable designers to develop cost- and space-efficient solutions.

Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and

overtemperature protection.

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 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 fast-acting fuse with a maximum rating of 6A (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.

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 (Maximum rated power = Vo,set x Io,max).

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 turn the power module on and off, the user must

supply a switch (open collector or equivalent) to

control the voltage (V_on/off) between the ON/OFF

terminal and the V_IN(-) terminal (Figure 40). Logic low

is –0.7V ≤ V_on/off≤ 1.2V. The maximum I_on/offduring

a logic low is 1mA, the switch should be maintain a

logic low level while sinking this current.

Remote Sense

Remote sense minimizes the effects of distribution

losses by regulating the voltage at the remote-sense

connections (See Figure 41). 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:

Connecting an external resistor (R_trim-down) between

the TRIM pin and the Vo(-) (or Sense(-)) pin

decreases the output voltage set point. To maintain

set point accuracy, the trim resistor tolerance should

be ±0.1%.

The following equation determines the required

external resistor value to obtain a percentage output

voltage change of Δ%

[VO(+) – VO(–)] – [SENSE(+) – SENSE(–)] ≤ 0.5 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.

Feature Description (Continued)

Overcurrent Protection

Tref

To provide protection in a fault (output overload)

condi¬tion, the module is equipped with internal

current-limiting circuitry, and can endure current

limiting continuously. At the instance of current-limit

inception, the output current begins to tail-out. When

an overcurrent condition exists beyond a few

seconds, the module enters a “hiccup” mode of

opera¬tion, whereby it shuts down and automatically

attempts to restart upon cooling. While the fault

condition exists, the module will remain in this hiccup

mode, and can remain in this mode until the fault is

cleared. The unit operates normally once the output

current is reduced back into its specified range.

Air Flow

Figure 43. T_refTemperature Measurement

Location.

Output Over Voltage Protection

The output overvoltage protection clamp consists of

control circuitry, independent of the primary regulation

loop, that monitors the voltage on the output

terminals. This control loop has a higher voltage set

point than the primary loop (See the overvoltage

clamp values in the Feature Specifications Table). In

a fault condition, the overvoltage clamp ensures that

the output voltage does not exceed Vo,ovsd, max.

This provides a redundant voltage-control that

reduces the risk of output overvoltage.

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 (T_A)

for natural convection and up to 2m/s (400 ft./min) are

shown in the respective Characteristics Curves

section.

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 between the

undervoltage lockout limit and the minimum operating

input voltage.

Overtemperature Protection

To provide protection under certain fault conditions,

the unit is equipped with a thermal shutdown circuit.

The unit will shutdown if the thermal reference point

Tref (Figure 43), exceeds 125^oC (typical), but the

thermal shutdown is not intended as a guarantee that

the unit will survive temperatures beyond its rating.

The module will automatically restarts after it cools

down.

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.

suggested Pb-free solder paste is Sn/Ag/Cu (SAC).

The recommended linear reflow profile using

Sn/Ag/Cu solder is shown in Fig. 51.

Surface Mount Information (continued)

Tin Lead Soldering

The recommended linear reflow profile using Sn/Pb

solder is shown in Figure 49 and 50. For reliable

soldering the solder reflow profile should be

established by accurately measuring the modules CP

connector temperatures.

Storage and Handling

The recommended storage environment and handling

procedures for moisture-sensitive surface mount

packages is detailed 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 humidity.

Lead Free Soldering

Post Solder Cleaning and Drying

Considerations

The –Z version SMT modules of EQW 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.

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 (AN04-001).
