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.
