AHE28XXS SERIES

28V Input, Single Output

ADVANCED ANALOG

HYBRID-HIGH RELIABILITY

DC/DC CONVERTERS

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 modu-

lated 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 17 to 40 VDC Input Range (28 VDC 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 re-

sponse for superior line and load transient character-

istics and offers greater reliability and radiation toler-

ance than devices incorporating optical feedback cir-

cuits.

n 15 and 20 Watts 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 en-

vironments.

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

These converters are manufactured in a facility certi-

fied to MIL-PRF-38534. All processes used to manu-

facture these converters have been qualified to enable

Advanced Analog to deliver compliant devices.

n 325,000 hour MTBF at 85°C (AUC)

Two screening grades are available to satisfy a wide

range of requirements. The CH grade converters are

fully compliant to MIL-PRF-38534 for class H. The HB

grade converters are processed to full class H screen-

ing but do not have class H element evaluation as re-

quired by MIL-PRF-38534. Both grades are fully tested

and operate over the full military temperature range

without derating of output power. Variations in electri-

cal, mechanical and screening can be accommodated.

Extensive computer simulation using complex

modeling enables rapid design modification to

be provided. Contact Advanced Analog with spe-

cific requirements.
