HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
AFL50XXD SERIES
50V 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, +50V, +120V or +270 V
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 550
KHz. 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.
