HYBRID-HIGH RELIABILITY

DC/DC CONVERTER

AFL120XXD SERIES

120V Input, Dual Output

Description

The AFL Series of DC/DC converters feature high power

density with no derating over the full military temperature

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

of converters providing single and dual output voltages

and operating from nominal +28V or +270V inputs with

output power ranging from 80W to 120W. For applications

requiring higher output power, individual converters

can be operated in parallel. The internal current sharing

circuits assure equal current distribution among the

paralleled converters. This series incorporates International

Rectifier’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 550KHz. Multiple converters

can be synchronized to a system clock in the 500KHz

to 700KHz 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

enclosure variations, utilizing copper core pins to

minimize resistive DC losses. Three lead styles are

available, each fabricated with International Rectifier’s

rugged ceramic lead-to-package seal assuring long

term hermeticity in the most harsh environments.
