description
Designed to convert fixed volt-
ages into an isolated voltage, the
VAT2-SMT series is well suited for
providing board-mount local sup-
plies in a wide range of applica-
tions, including mixed analog/digi-
tal circuits, test & measurement
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.
