VEFT1-SMT Dual Output Series Dc-Dc Converter
Rev. 11-2005
Description
Designed to convert fixed volt-
ages into an isolated voltage, the
VEFT1-SMT dual series is well
suited for providing board-mount
local supplies in a wide range of
applications, including mixed ana-
log/digital circuits, test & meas-
urement equip., process/machine
controls, datacom/telecom fields,
etc...
The semi-regulated output can be
followed by 3-terminal regulators
to provide output protection, in
addition to output regulation.
