AHF2815T SERIES

28V Input, Triple Output

HYBRID-HIGH RELIABILITY

DC/DC CONVERTER

Description

The AHF2815T Series of DC/DC converters provide

8W of power and an extended temperature range for

use in military and industrial applications. Designed to

the nominal input requirements of MIL-STD-704, these

devices have nominal 28VDC inputs with +5V and ±15V

triple outputs to satisfy a wide range of requirements.

The basic circuit utilizes a pulse width modulated, feed

forward topology at a nominal switching frequency of

550KHz. Input to output isolation is achieved through

the use of transformers in the forward and feedback

circuits.

AHF

Features

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

ꢀ 5V, ±15V Output

ꢀ Infinite Short Circuit and Overload Protection

ꢀ 8W Output Power

ꢀ Fast Loop Response for Superior Transient

Characteristics

ꢀ Operating Temperature Range from -55°C to

+125°C Available

ꢀ Popular Industry Standard Pin-Out

ꢀ Resistance Seam Welded Case for Superior

Long Term Hermeticity

ꢀ Efficiency Up to 75%

ꢀ Shutdown from External Signal

ꢀ 400,000 Hour MTBF at 85%

The proprietary magnetic feedback circuit provides for

an extremely wide bandwidth control loop with a high

phase margin. The closed loop frequency response of

this converter family extends to approximately 50KHz,

resulting in superior line and load transient characteristics.

This feedback method is also inherently temperature

and radiation insensitive. This gives the AHF Series

an important advantage over converters that incorporate opto-

couplers in their design.

ꢀ Constant Switching Frequency (550KHz Nominal)

ꢀ Standard Microcircuit Drawing Available

Manufactured in a facility 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.
