PD - 94435B 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 AFL complete family of converters providing single and dual output voltages and operating from nominal +28V or Features +270V inputs with output power ranging from 80W to 120W. For applications requiring higher output power, 160V To 400V Input Range multiple converters can be operated in parallel. The 5V, 6V, 9V, 12V, 15V and 28V Outputs Available internal current sharing circuits assure equal current 3 High Power Density - up to 84W/in distribution among the paralleled converters. This series incorporates International Rectifiers proprietary Up To 120W Output Power magnetic pulse feedback technology providing Parallel Operation with Stress and Current Sharing optimum dynamic line and load regulation response. Low Profile (0.380 ) Seam Welded Package This feedback system samples the output voltage at Ceramic Feedthru Copper Core Pins the pulse width modulator fixed clock frequency, nominally 550KHz. Multiple converters can be High Efficiency - to 87% synchronized to a system clock in the 500 KHz to 700KHz Full Military Temperature Range Continuous Short Circuit and Overload range or to the synchronization output of one converter. Protection Undervoltage lockout, primary and secondary Remote Sensing Terminals referenced inhibit, softstart and load fault protection are provided on all models. Primary and Secondary Referenced Inhibit Functions Line Rejection > 60dB - DC to 50KHz These converters are hermetically packaged in two External Synchronization Port enclosure variations, utilizing copper core pins to Fault Tolerant Design minimize resistive DC losses. Three lead styles are Dual Output Versions Available available, each fabricated with International Rectifiers Standard Microcircuit Drawings Available 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.
