APPLICATIONS
The B-X(S)D-1WP 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.
