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
