VFSD1-SIP Series Dc-Dc Converter
Rev. 12-2005
Description
Features
Designed to convert fixed voltages into an isolated voltage, the
VFSD1-SIP series is well suited for
providing board-mount local supplies in a wide range of applications, including mixed analog/digital circuits, test & measurement
equip., process/machine controls,
datacom/telecom fields, etc...
·Isolated 1 W output
·Temperature range: -40°C~+85°C
·Unregulated
·High efficiency to 80%
·Single voltage output
·Small footprint
·SIP package style
·Industry standard pinout
·UL94-V0 package
·No heatsink required
·3K 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.
