AFL270XXD 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 or +270 volt

inputs with output power ranging from 80 to 120 watts.

For applications requiring higher output power, indi-

vidual converters can be operated in parallel. The inter-

nal current sharing circuits assure equal current distri-

bution among the paralleled converters. This series in-

corporates Advanced Analog’s proprietary magnetic

pulse feedback technology providing optimum dynamic

line and load regulation response. This feedback sys-

tem samples the output voltage at the pulse width modu-

lator fixed clock frequency, nominally 550 KHz. Multiple

converters can be synchronized to a system 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 models.

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 processed and

screened to the class H requirement, but may not nec-

essarily meet all of the other MIL-PRF-38534 require-

ments, e.g., element evaluation and Periodic Inspection

(P.I.) not required. Both grades are tested to meet the

complete group “A” test specification over the full mili-

tary temperature range without output power deration.

Two grades with more limited screening are also avail-
