APPLICATIONS
The 2B-X(S)D 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℃. Pin
compatibility with the B_XLS series ensures
ease of upgradeability.
