APPLICATIONS
The 2B-XNM series of DC/DC Converters is
particularly suited to isolating and/or
converting DC power rails. The galvanic
isolation allows the device to be conï¬gured to
provide an isolated negative rail in systems
where only positive rails exist.The wide
temperature range guarantees startup from
â40°C and full 2 watt output at 85°C. Pin
compatibility with the B-XN(S)D-1W ensures
ease of upgradeability.
