Delta DVSB2853R3D/K-XXX High reliability hybrid dc-dc converter Datasheet

DVSB2800D Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
FEATURES
The DVSB 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 DVSB series is a fault tolerant magnetic
feedback circuit. Operating at a nominal fixed
frequency of 325 kHz per stage, these regulated,
isolated units utilize 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 MILPRF-38534 and MIL-STD-883.
This product may incorporate one or more of the
following U.S. patents:
