HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
PD - 94461C
AFL270XXD SERIES
270V 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.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are fabricated utilizing DSCC
qualified processes. For available screening options,
refer to device screening table in the data sheet.
Variations in electrical, mechanical and screening can
be accommodated. Contact IR Santa Clara for special
requirements.
