ATR28XXD SERIES

28V Input, Dual Output

HYBRID-HIGH RELIABILITY

DC/DC CONVERTER

Description

The ATR28XXD 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-704D input requirements, these devices

have nominal 28VDC inputs with ±12V and ±15V dual

outputs to satisfy a wide range of requirements. The

circuit design incorporates a pulse width modulated

single forward topology operating in the feed-forward

mode at a nominal switching frequency of 550KHz.

Input to output isolation is achieved through the use of

transformers in the forward and feedback circuits.

ATR

Features

ꢀ 16V to 40VDC Input Range (28VDC Nominal)

±12V and ±15V Outputs Available

ꢀ

ꢀ Indefinite Short Circuit and Overload Protection

ꢀ 35W/in³Power Density

ꢀ 30W Output Power

ꢀ Fast Loop Response for Superior Transient

Characteristics

ꢀ Operating Temperature Range from -55°C to

+125°C

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 feedback circuits.

ꢀ Popular Industry Standard Pin-Out

ꢀ Resistance Seam Welded Case for Superior

Long Term Hermeticity

ꢀ Ceramic Feed-thru Pins

ꢀ External Synchronization

ꢀ High Efficiency

Three standard temperature grades are offered with

screening options. Refer to Part Number section. They

can be provided in a standard plug-in package for PC

mounting or in a flanged package for more severe

environments.

ꢀ Shutdown from External Signal

ꢀ Military Screening

ꢀ 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.

Extensive computer simulation using complex modeling

enables rapid design modification to be provided.
