ATW28XXS SERIES

28V Input, Single Output

HYBRID-HIGH RELIABILITY

DC/DC CONVERTER

Description

ATW

The ATW28XXS Series of DC/DC converters feature

high power density and an extended temperature range

for use in military and industrial applications. Designed

to MIL-STD-704 input requirements, these devices

operate with a nominal 28VDC input and are available

with single outputs at 5V,12V and 15V. The circuit design

incorporates a pulse width modulated push-pull

topology operating in the feed-forward mode at a

nominal switching frequency of 270KHz. Input to output

isolation is achieved through the use of transformers in

the forward and feedback circuits.

Features

n 19V to 40VDC Input Range (28VDC Nominal)

n 30W Output Power

n Indefinite Short Circuit and Overload Protection

n 22.8W/in³Power Density

n Fast Loop Response for Superior Transient

Characteristics

n Operating Temperature Range from -55°C to

+125°C Available

The advanced feedback design provides fast loop

response for superior line and load transient

characteristics and offers greater reliability and radiation

tolerance than devices incorporating optical elements

in the feedback circuits.

n Popular Industry Standard Pin-Out

n Resistance Seam Welded Case for Superior

Long Term Hermeticity

n Efficiencies up to 83%

n Shutdown from External Signal

n Military Screening

Three standard temperature grades are offered. Refer

to Part Number section. These devices are provided in

a flanged package for secure mounting in severe

environments.

n 250,000 hour MTBF at 85°C

n Standard Microcircuit Drawings Available

Manufactured in a facility fully qualified to MIL-PRF-

38534, these converters are fabricated utilizing DSCC

qualified processes. For available screening options,

refer to device screening table in the data sheet.

Variations in electrical, mechanical and screening can

be accommodated. Contact IR Santa Clara for special

requirements.
