AFL270XXS SERIES

270V Input, Single Output

ADVANCED ANALOG

HIGH RELIABILITY

HYBRID DC/DC CONERTERS

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, multiple

converters can be operated in parallel. The internal cur-

rent sharing circuits assure equal current distribution

among the paralleled converters. This series incorpo-

rates Advanced Analog’s proprietary magnetic pulse

feedback technology providing optimum dynamic line

and load regulation response. This feedback system

samples the output voltage at the pulse width modulator

fixed clock frequency, nominally 550 KHz. Multiple con-

verters 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.

n Dual Output Versions Available

n Standard Military Drawings Available

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

damanding applications. Variations in electrical,

mechanical and screening can be accommo-

dated. Contact Advanced Analog for special re-

quirements.
