ROHM BD768xFJ-LB quasi-resonant DC/DC converter

ROHM’s BD768xFJ-LB, low-noise, quasi-resonant control, DC/DC converter provides an optimum system for all products that include an electrical outlet. Quasi-resonant operation enables soft switching and helps to keep EMI low. A high degree of design flexibility is achieved using switching MOSFET and current detection resistors as external devices.

The built-in, brownout function monitors the input voltage as part of system optimisation. The burst-mode function reduces input power at low power. The series includes various protection functions, such as a soft-start function, burst function, per-cycle overcurrent limiter function, overvoltage protection function, overload protection function and brownout function. It also includes a gate-clamp circuit.

This series is suitable for high-voltage industrial applications, including industrial equipment, AC adapters and household appliances.
