APPLICATIONS

APPLICATIONS

The B-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 1 watt output at 85°C.

For lower ripple,refer to output ripple reduction

section.
