BP6211C
Description
The BP6211C is a high-performance, high-integration, self-biased synchronous rectifier (SR) with a 60 V MOSFET integrated for flyback converters. It can replace the secondary diode rectifier for higher efficiency and power density.
The BP6211C supports discontinuous conduction mode (DCM), quasi-resonant (QR) and continuous conduction mode (CCM) operations. Robust operation in CCM is enabled with adaptive gate drive and faster turn-off speed with 4 A sink current and ultra-short turn-off delay.
The internal ringing detection circuitry prevents the IC from falsely turning on during DCM or QR operations. The internal turn-on blanking function prevents an accidental turn-off due to parasitic ringing. Ultra-short turn-on delay increases SR MOSFET conduction time to improve efficiency.
The BP6211C generates its own supply voltage without requiring auxiliary winding for low-side or high-side rectification. This feature makes it suitable for charger applications with a very low...
