APPLICATIONS
The B-XNS-1W series of DC/DC converters
is particular-ly suited to isolating and/or
converting DC power rails. The galvanic
isolation allows the device to be configured 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.
