DescrIptIOn
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
certified and qualified MIL-PRF-38534 production facility and
packaged in hermetically sealed steel cases. They are ideal for
use in programs requiring high reliability, small size, and high
levels of radiation hardening assurance.
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.
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.
