AFL120XXS SERIES

120V Input, Single Output

ADVANCED ANALOG

HIGH RELIABILITY

HYBRID DC/DC CONVERTERS

Description

The AFL Series of DC/DC converters feature high power

density with no derating over the full military tempera-

ture range. This series is offered as part of a complete

family of converters providing single and dual output

voltages and operating from nominal +28, +50, +120 or

+270 volt inputs with output power ranging from 80 to

120 watts. For applications requiring higher output

power, multiple converters can be operated in parallel.

The internal current sharing circuits assure equal cur-

rent distribution among the paralleled converters. This

series incorporates Advanced Analog’s proprietary mag-

netic pulse feedback technology providing optimum

dynamic line and load regulation response. This feed-

back system samples the output voltage at the pulse

width modulator fixed clock frequency, nominally 550

KHz. Multiple converters can be synchronized to a sys-

tem clock in the 500 KHz to 700 KHz 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 mod-

els.

These converters are hermetically packaged in two en-

closure variations, utilizing copper core pins to mini-

mize resistive DC losses. Three lead styles are avail-

able, each fabricated with Advanced Analog’s rugged

ceramic lead-to-package seal assuring long term

hermeticity in the most harsh environments.

Manufactured in a facility fully qualified to MIL-PRF-

38534, these converters are available in four screening

grades to satisfy a wide range of requirements. The CH

grade is fully compliant to the requirements of MIL-PRF-

38534 for class H. The HB grade is fully processed and

screened to the class H requirement, but does not have

material element evaluated to the class H requirement.

Both grades are tested to meet the complete group “A”

test specification over the full military temperature range

without output power deration. Two grades with more

limited screening are also available for use in less de-

manding applications. Variations in electrical, me-

chanical and screening can be accommodated.

Contact Advanced Analog for special require-

ments.
