APPLICATIONS

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.
