ROHM's BM2SCQ12xT-LBZ series is a quasi-resonant AC/DC converter that provides an optimum system for all products that have electrical outlets. Quasi-resonant operation enables soft switching and helps to keep the EMI low. This IC can be designed-in easily because it includes the 1700 V/4 A SiC (silicon carbide) MOSFET. Design with a high degree of flexibility is achieved with current detection resistors as external devices. The burst operation reduces an input power at light load. BM2SCQ12xT-LBZ series includes various protection functions, such as soft start function, burst operation, overcurrent limiter per cycle, overvoltage protection function, and overload protection function.
