FEATURES
DESCRIPTION
The NKE sub-miniature series of DC/DC Converters
is particularly suited to isolating and/or converting
DC power rails. A smaller package size, improved
effi ciency, lower output ripple and 3kVDC isolation
capability through state of the art packaging and
improved technology. The galvanic isolation allows
the device to be confi gured to provide an isolated
negative rail in systems where only positive rails
exist. The wide temperature range guarantees
startup from –40°C and full 1 watt output at 85°C.
