Overview

PD - 94462E AFL27003R3S HIGH RELIABILITY HYBRID 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 +28 or +270 volt inputs with output power ranging from 80 to 120 watts.
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 550 KHz.
Multiple converters can be synchronized to a system clock in the 500 KHz to 700 KHz 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.
Manufactured in a facility fully qualified to MIL-PRF38534, these converters are available in four screening grades to satisfy a wide range of requirements.
The CH grade is fully compliant to the requirements of MIL-PRF38534 for class H.
The HB grade is fully processed and screened to the class H requirement, but does not have material element evaluated to the class H requirement.
Both grades are tested to meet the complete group “A” test specification over the full military temperature range without output power deration.
