1 / 10 page  09/11/02 www.irf.com 1 ADVANCED ANALOG HIGH RELIABILITY HYBRID DC/DC CONVERTERS AFL270XXD SERIES The AFL Series of DC/DC converters feature high power density with no derating over the full military tempera- ture 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, indi- vidual converters can be operated in parallel. The inter- nal current sharing circuits assure equal current distri- bution among the paralleled converters. This series in- corporates Advanced Analog’s proprietary magnetic pulse feedback technology providing optimum dynamic line and load regulation response. This feedback sys- tem samples the output voltage at the pulse width modu- lator 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, soft-start and load fault protection are provided on all models. These converters are hermetically packaged in two en- closure variations, utilizing copper core pins to mini- mize resistive DC losses. Three lead styles are avail- able, each fabricated with Advanced Analog’s rugged ceramic lead-to-package seal assuring long term hermeticity in the most harsh environments. Description n 160 To 400 Volt Input Range n ±5, ±12, and ±15 Volts Outputs Available n High Power Density - up to 70 W / in3 n Up To 100 Watt Output Power n Parallel Operation with Power Sharing n Low Profile (0.380") Seam Welded Package n Ceramic Feedthru Copper Core Pins n High Efficiency - to 87% n Full Military Temperature Range n Continuous Short Circuit and Overload Protection n Output Voltage Trim n Primary and Secondary Referenced Inhibit Functions n Line Rejection > 60 dB - DC to 50KHz n External Synchronization Port n Fault Tolerant Design n Single Output Versions Available n Standard Military Drawings Available Features AFL 270V Input, Dual Output Manufactured in a facility fully qualified to MIL-PRF- 38534, 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-H- 38534 for class H. The HB grade is processed and screened to the class H requirement, but may not nec- essarily meet all of the other MIL-PRF-38534 require- ments, e.g., element evaluation and Periodic Inspection (P.I.) not required. Both grades are tested to meet the complete group “A” test specification over the full mili- tary temperature range without output power deration. Two grades with more limited screening are also avail- able for use in less demanding applications. Varia- tions in electrical, mechanical and screening can be accommodated.
