ADVANCED ANALOG

HIGH RELIABILITY

HYBRID DC/DC CONVERTER

Description

The AFL Series of DC/DC converters feature high power

density with no derating over the full military tempera-

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

family of converters providing single and dual output

voltages originally created to operate over a nominal

input voltage range of 28 to 270 volts with output power

ranging from 66 to 120 watts. For applications requir-

ing higher output power, multiple converters can be op-

erated in parallel. The internal current sharing circuits

assure equal current distribution among the paralleled

converters. This series incorporates Advanced Analog’s

proprietary magnetic pulse feedback technology pro-

viding optimum dynamic line and load regulation re-

sponse. This feedback system samples the output volt-

age at the pulse width modulator fixed clock frequency,

nominally 550 KHz. Multiple converters can be synchro-

nized 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 refer-

enced inhibit, soft-start and load fault protection are pro-

vided 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-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-
