DESCRIPTION
The TKD series of dual-output DC/DC converters provides
high power and full isolation in a low cost, single-board
design package. The TKD series provides highly reliable,
onboard conversion of telecom and datacom input voltages
to isolated low output voltages without the need for a
heatsink. The TKD series is ideally suited for Distributed
Power Architectures (DPA), telecommunications equip-
ment, LAN/WAN, and data processing applications.
