| 07/25/03 www.irf.com 1 advanced analog radiation tolerant dc/dc converters description 30 watts output power available in 5, 12 and 15 volt outputs 16 - 40 vdc input range (28 vdc nominal) total ionizing dose > 25krads (si) no see to let > 60 mev-cm 2 /mg -55c to +125c operating range indefinite short circuit protection external synchronization shutdown from external signal flexible mounting fully isolated - input to output and to case complimentary emi filter available electrical performance similar to atr28xxd series features amr 28v input, dual output amr28xxd series the amr28xxd series of dc/dc converter modules has been specifically designed for operation in moder- ate radiation environments supplementing the higher radiation performance available in the advanced ana- log art2815t converter series. environments pre- sented to space vehicles operating in low earth orbits, launch boosters, orbiting space stations and similar applications requiring a low power, high performance converter with moderate radiation hardness perfor- mance will be optimally served by the amr28xxd se- ries. the physical configuration of the amr28xxd series permits mounting directly to a heat conduction surface without the necessity of signal leads penetrating the heat sink surface. this package configuration permits greater independence in mounting and more mechani- cal security than traditional packages. advanced analog?s rugged ceramic seal pins are used exclusively in the package thereby assuring long term hermeticity. the amr28xxd has been designed for high density using chip and wire hybrid technology that complies with mil-prf-38534. finished product are fabricated in a facility fully qualified to mil-prf-38534. the stan- dard processing adopted for the amr28xxd is an en- hanced version of the requirements of mil-prf-38534 for class h including element evaluation. applicable generic lot qualification test data including radiation performance can be made available on request. varia- tions to the standard screening can be accommodated. consult advanced analog for special requirements. pd - 94690
