AFL50XXS SERIES

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, individual converters can be operated in paral-

lel. The internal current sharing circuits assure equal

current 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-H-

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

screened to the class H requirement, may not neces-

sarily meet all of the other MIL-PRF-38534 requirements,

e.g., element evaluation and Periodic Inspection (P.I.)

not required. Both grades are tested to meet the com-

plete group “A” test specification over the full military
