HIGH RELIABILITY HYBRID

DC-DC CONVERTERS

DESCRIPTION

The DVAB series of high reliability DC-DC converters

is operable over the full military (-55 °C to +125 °C)

temperature range with no power derating. Unique

to the DVAB series are independent dual control

loops which provide tight regulation and zero cross

regulation error while maintaining high

efficiency. Operating at a nominal fixed frequency of

325 kHz, per stage, these regulated, isolated units

utilize a high speed magnetic feedback design and

well controlled undervoltage lockout circuitry to

eliminate slow start-up problems.

These converters are designed and manufactured in

a facility qualified to ISO9001 and certified to MIL-

PRF-38534 and MIL-STD-883.

This product may incorporate one or more of the

following U.S. patents:
