SRK1000 / SRK1000A /SRK1000B Datasheet Adaptive synchronous rectification controller for flyback converter SOT23-6L Product status link SRK1000 / SRK1000A /SRK1000B Product summary Order code SRK1000 SRK1000ATR SRK1000BTR Package SOT23-6L Packing Tape and reel Product label 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. Application • Battery chargers / quick chargers • Adapters • USB power delivery (profile 3) Description SRK1000 / SRK1000A /SRK1000B are controllers intended for secondary side synchronous rectification (SR) in flyback converters, suitable for operation in QR and mixed CCM/DCM fixed frequency circuits. They provide a high-current gate-drive output, capable of driving N-channel Power MOSFETs. The control scheme o.
