Overview
PD - 94448E AFL12003R3S 120V Input, 3.
3V 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 66W 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 500KHz to 700KHz range or to the synchronization output of one converter.
Under voltage 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 leadto-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.
