ATR28XXS SERIES

28V Input, Single Output

HYBRID - HIGH RELIABILITY

DC-DC CONVERTER

Description

The ATR28XXS 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 3.3V, 5V, 12V and

15V single 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

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

n 3.3V, 5V, 12V and 15V Outputs Available

n Indefinite Short Circuit and Overload

Protection

n Up to 35W/in³Power Density

n 30W Output Power Models

n Fast Loop Response for Superior Transient

Characteristics

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.

n Operating Temperature Range from

-55°C to +125°C

Three standard temperature grades are offered with

screening options. Refer to Part Number section. These

devices can be provided in a standard plug-in package

for PC mounting or in a flanged package for more

severe environments.

n Popular Industry Standard Pin-Out

n Resistance Seam Welded Case for Superior

Long Term Hermeticity

n Ceramic Feed-thru Pins

n External Synchronization

n Efficiencies up to 84%

n Shutdown from External Signal

n Military Screening

Manufactured in a facility fully qualified to MIL-PRF-

38534, these converters are fabricated utilizingDLA

Land and Maritime qualified processes. For available

screening options, refer to device screening table in

the data sheet. Variations in electrical, mechanical and

screening can be accommodated.

n Standard Microcircuit Drawings Available

Extensive computer simulation using complex modeling

enables rapid design modification to be provided.
