SRK1000
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 k Hz.
- 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)
