AHF28XX SERIES

28V Input, Single and Dual Output

ADVANCED ANALOG

HYBRID-HIGH RELIABILITY

DC/DC CONVERTERS

Description

The AHF Series of DC/DC converters feature single or

dual outputs over the full military temperature range.

No derating in output power is required, making them

suitable for use in rugged military applications. The low

profile, small outline package is ideally suited to the

tight board space requirements of many industrial and

aerospace applications. Designed for nominal 28Vdc

inputs, this family of converters will meet the require-

ments of MIL-STD-704D. The basic circuit utilizes a

pulse width modulated, feed-forward topology at a nomi-

nal switching frequency of 550KHz. Input to output iso-

lation is achieved through the use of transformers in

the forward and feedback circuits.

Features

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

n Single and Dual Outputs

n 12 Watts Output Power

22.8 W/in3 Power Density

Low Input / Output Noise

(50mA/60mVp-p max. respectively)

Indefinite Short Circuit and Overload

Protection

Wideband Control Loop for

Superior Transient Characterstics

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 character-

istics. This feedback method is also inherently tem-

perature and radiation insensitive. This gives the AHF

Series an important advantage over converters that

incorporate opto-couplers in their design.

n No Derating for -55°C to +125°C Opertation

Constant Switching Frequency

(550KHz Nominal)

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. Four

screening grades are available to satisfy a wide range

of requirements.The CH grade converters are fully com-

pliant to MIL-PRF-38534 class H. The HB grade con-

verters are processed to full MIL-PRF-38534 screen-

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

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

and operate the full military temperature range without

derating of output power. Industrial and commercial

grades are also available. Variations are electrical,

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.
