This is the product guarantees long time support in the
Industrial market.

BD768xFJ series is a Quasi-resonant controller type
DC/DC converters that provide an optimum system for
all products that include an electrical outlet.
Quasi-resonant operation enables soft switching and
helps to keep EMI low. Design with a high degree of
flexibility is achieved with switching MOSFETs and
current detection resistors as external devices.
The built-in brown out function monitors the input
voltage as part of system optimization. The burst mode
function reduces input power at low power.
BD768xFJ series include various protection functions,
such as a soft start function, burst function, per-cycle
over-current limiter function, overvoltage protection
function, overload protection function, and brown out

BD768xFJ series include a gate-clamp circuit for
optimal driving SIC-MOSFET.
