APPLICATIONS
The B-XM-2W 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 2 watt output at 85°C. Pin
compatibility with the B-X(S)D-1W ensures
ease of upgradeability.
