PART NUMBER: VAT2-SMT series
DESCRIPTION: dc-dc converter
description
features
·isolated 2 W output
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...
·temperature range: -40°C~+85°C
·unregulated
·high efficiency to 85%
·dual voltage output
·small footprint
·SMD package style
·industry standard pinout
·UL94-V0 package
·no heatsink required
·1K Vdc isolation
The semi-regulated output can be
followed by 3-terminal regulators
to provide output protection, in
addition to output regulation.
·high power density
·no external component required
·low cost
