BM2SCQ121T-LBZ ROHM

Datasheet Quasi-resonant AC/DC Converter Built-in 1700 V SiC-MO SFET BM2SCQ12xT-LBZ Series General Description Key Specifications This is the product guarantees long time support in Operating Power Supply Voltage Range: industrial market. VCC: 15.0 V to 27.5 V BM2SCQ12xT-LBZ series is a quasi-resonant AC/DC DRAIN: 1700 V (Max) converter that provides an optimum system for all Normal Operating Current: 2000 A (Typ) products which has an electrical outlet. Quasi-resonant Burst Operating Current: 500 A (Typ) operation enables soft switching and helps to keep the Maximum Operating Frequency: 120 kHz (Typ) EMI low. Operating Temperature: -40 C to +105 C This IC can be designed easily because it includes the 1700 V/4 A SiC (Silicon-Carbide) MOSFET. Design with a high degree of flexibility is achieved with Package W (Typ) x D (Typ) x H (Max) current detection resistors as external devices. The burst TO220-6M 10.0 mm x 4.5 mm x 25.6 mm operation reduces an input power at light load. BM2SCQ12xT-LBZ series includes various protection functions, such as soft start function, burst operation, over current limiter per cycle, over-voltage protection function, overload protection function.
