Key features

Key features
Secondary side synchronous rectification controller optimized for flyback converter. Suitable for QR and mixed CCM/DCM fixed frequency operation. Wide V_cc operating voltage range 3.75 to 32 V. CC regulation operation down to 2 V output supported. Very low quiescent current in low consumption mode (160 μA). High-voltage sensing input for SR MOSFET drain-source voltage (100 V AMR). Operating frequency up to 300 kHz. High-current gate-drive output for N-MOSFET. Fast turn-on with minimum delay time and adaptive turn-off logic. Programmable min. T_ON and fixed min. T_OFF(3 options: SRK1000, SRK1000A, SRK1000B). Low consumption mode entry by primary side burst-mode detection or by detection of SR MOSFET conduction lower than programmed min T_ON. SOT23-6L package.
