SRK1000ATR

Adaptive synchronous rectification controller for flyback converter

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameSOT23-6L

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...

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.
