PD-94458C HYBRID-HIGH RELIABILITY DC/DC CONVERTER AFL28XXD SERIES 28V 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 plete 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.
