The B-XM-1W series of DC/DC converters is

particularly 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.
