ETC DVSA2805D

DVSA2800D Series
HIGH RELIABILITY HYBRID
DC-DC CONVERTERS
DESCRIPTION
FEATURES
The DVSA 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 DVSA series is a magnetic feedback circuit
that is radiation immune. Operating at a nominal
fixed frequency of 450 kHz, 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, compliant to AS9000,
and certified to MIL-PRF-38534 and MIL-STD-883.
