HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
AFL50XXS SERIES
50V Input, Single 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 +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 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
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.
