AFL28XXD SERIES  
28V Input, Dual 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,  
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.
