The BP62110 is a high-performance synchronous rectifier (SR) controller designed for high efficiency and power density flyback converter.

The BP62110 is compatible with discontinuous conduction mode (DCM), quasi-resonant (QR) and continuous conduction mode (CCM) operations. Robust operation in CCM is further enhanced with pre-turn-off control method,intelligent gate-driver-voltage, faster turn-off speed with 4A sink current and short turn-off delay.

The BP62110 has multiple features that improve performance. The internal ringing detection circuitry prevents the BP62110 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 device generates its own supply voltage without requiring auxiliary winding for low-side or high-side rectification. The feature makes it suitable for charger applications with a low output voltage requirement, or any other adapter applications.

The BP62110 is available in an SOT23-6 package.
