    Key features
    Key features
    • Secondary side synchronous rectification controller optimized for flyback converter.
    • Suitable for QR and mixed CCM/DCM fixed frequency operation.
    • Wide Vcc 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. TON and fixed min. TOFF (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 TON.
    • SOT23-6L package.
