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. |
