The B-X(S)D-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.
For lower ripple,refer to output ripple reduction
section.
