A minimum load of 2% of full load should be used on outputs at

TID of 100 kRad(Si) or greater to ensure tight regulation over the

full input range. The converter should not be inhibited or oper-

ated below 19 Vin above 5x10⁴rad(Si) total dose.

The SMRT28 Series™ of DC/DC converters offers up to 35

watts of power in a radiation tolerant design. The low profile

SMRT28 converters are manufactured in Interpoint’s fully certi-

fied and qualified MIL-PRF-38534 production facility and pack-

aged in hermetically sealed steel cases. They are ideal for use in

programs requiring high reliability, small size, and high levels of

radiation hardening assurance.

Two independent feedback loops are used to regulate the dual

and triple outputs, one feedback loop regulates the two-phased

single output. Each set of outputs is electrically isolated from the

other and from the input. This product configuration eliminates

cross regulation effects between output sets.

The SMRT28 converters are switching regulators which use a

two-phase, phase shifted flyback design with a nominal switching

frequency of 300 kHz. Close regulation is maintained with

advanced constant frequency pulse width modulation design

techniques. The SMRT28’s feed-forward compensation and

discontinuous topologies provide high levels (80 dB peak) of

input-to-output ripple rejection.

Configurations:

•ꢀSingleꢀOutput:ꢀOneꢀtwo-phaseꢀsingleꢀoutput

•ꢀDualꢀOutput:ꢀTwoꢀsingle-phaseꢀsingleꢀoutputs

•ꢀTripleꢀOutput:ꢀOneꢀsingle-phaseꢀindependentꢀ

Main output and one single-phase dual output.
