Quasi-resonant controllers designed to drive SCT2H12NZ SiC MOSFETs

Providing an optimum system for products that include an electrical outlet, Rohm's BD768xFJ-LB, low-noise, quasi-resonant control, DC-DC converter is now available from Digi-Key. 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. A built-in brownout function monitors the input voltage as part of system optimization. The burst-mode function reduces input power at low power. The BD768xFJ-LB 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. BD768xFJ-LB series includes a gate-clamp circuit for optimal driving SiC MOSFET. The series is ideal for high-voltage industrial applications, including industrial equipment, AC adaptors, and household appliances, says the company.
