AFL270XXS SERIES
270V Input, Single Output
HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
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,
multiple 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 500 KHz to 700KHz
range or to the synchronization output of one converter.
Undervoltage lockout, primary and secondary
referenced inhibit, softstart 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.
