PART NUMBER: VASD1-SIP series
DESCRIPTION: DC/DC converter
description
features
·isolated 1 W output
·temperature range: -40°C~+85°C
·unregulated
Designed to convert fixed volt-
ages into an isolated voltage, the
VASD1-SIP series is well suited
for providing board-mount local
supplies in a wide range of appli-
cations, including mixed
·high efficiency to 80%
·dual voltage output
·small footprint
·DIP package style
·industry standard pinout
·UL94-V0 package
analog/digital circuits, test &
measurement equip.,
process/machine controls, data-
com/telecom fields, etc...
·no heatsink required
·1K Vdc isolation
·power density 0.85 W/cm³
·no external component required
·low cost
The semi-regulated output can be
followed by 3-terminal regulators
to provide output protection, in
addition to output regulation.
