AHE28XXS SERIES

28V Input, Single Output

HYBRID-HIGH RELIABILITY

DC/DC CONVERTER

Description

The AHE28XXS 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 +5V, +12V and +15V

single outputs to satisfy a wide range of requirements.

The circuit design incorporates a pulse width modulated

push-pull topology operating in the feed-forward mode

at a nominal switching frequency of 250KHz. Input to

output isolation is achieved through the use of

transformers in the forward and feedback circuits.

AHE

Features

n 17V to 40VDC Input Range (28VDC Nominal)

5V, 12V and 15V Outputs Available

n Indefinite Short Circuit and Overload Protection

n 17 W/in³Power Density

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 15W and 20W Output Power Models

n Fast Loop Response for Superior Transient

Characteristics

n Operating Temperature Range from -55°C to

+125°C Available

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.

n Popular Industry Standard Pin-Out

n Resistance Seam Welded Case for Superior

Long Term Hermeticity

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 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. Contact IR Santa Clara with specific

requirements.

n 325,000 hour MTBF at 85°C (AUC)

n Standard Microcircuit Drawings Available
