VDSD2-SIP Series DC-DC Converter
Rev. 06-2006
Description
Features
Designed to convert fixed voltages into an isolated voltage, the
VDSD2-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 2 W output
·Temperature range: -40°C~+85°C
·Unregulated
·High efficiency to 87%
·Dual independent voltage output
·Small footprint
·SIP package style
·Industry standard pinout
·UL94-V0 package
·No heatsink required
·1K Vdc isolation
·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.
