AHP270XXS SERIES

270V Input, Single Output

HYBRID - HIGH RELIABILITY

DC/DC CONVERTER

Description

The AHP Series of DC/DC converters feature high power

density without derating over the full military temperature

range. This series is offered as lower cost alternatives to

the legendary AFL series with improved performance for

new design applications. The AHPs are form, fit and

functional replacement to the AFL series. The new AHP

series offers a full compliment of single and dual output

voltages operating from nominal +28V or +270V inputs

with output power ranging from 66W to 120W. For

applications requiring higher output power, multiple

converters can be operated in parallel. The internal current

sharing circuits assure equal current distribution among

the paralleled converters. Same as the AFL, the AHP

series incorporates International Rectifier’s proprietary

magnetic pulse feedback technology providing optimum

dynamic line and load regulation response. This feedback

system samples the output voltage at the pulse width

modulator fixed clock frequency, nominally 550KHz.

Multiple converters can be synchronized to a system clock

in the 500KHz to 700KHz range or to the synchronization

output of one converter. Undervoltage lockout, primary

and secondary referenced inhibit, soft-start and load fault

protection are provided on all models. Also included is

input over-voltage protection, a new protection feature

unique to the AHP.

These converters are hermetically packaged in two

enclosure variations, utilizing copper core pins to minimize

resistive DC losses. Three lead styles are available, each

fabricated with International Rectifier’s rugged ceramic

lead-to-package seal assuring long term hermeticity in

the most harsh environments.

n Dual Output Versions Available

n Standard Microcircuit Drawing 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.
