Description

The QW series power modules are isolated dc-dc converters that can deliver up to 20A of output current and provide a pre-

cisely regulated output voltage over a wide range of input voltages (VI = 36Vdc to 75Vdc). The modules achieve full load effi-

ciency of 91% at 3.3V output voltage, The open frame modules, available in both surface-mount and through-hole packaging,

enable designers to develop cost- and space-efficient solutions.

Standard features include remote On/Off, output voltage adjust-

ment, remote sense,overvoltage, overcurrent and overtemperature protection.

Absolute Maximum Ratings

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

device reliabiltiy.

Electrical Specifications

Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.

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 time-delay fuse with a

maximum rating of 5 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 sheet for further information.
