SRK1001 - Adaptive synchronous rectification controller

Description

The SRK1001 controller is designed for secondary side synchronous rectification (SR) in flyback converters, suitable for operation in QR and mixed CCM/DCM fixed frequency circuits.

It provides a high-current gate-drive output capable of driving N-channel Power MOSFETs.

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 3.7 to 32 V.
  • CC regulation operation down to 2V output supported.
  • Very low quiescent current in low consumption mode (170 µA).
  • High-voltage sensing input for SR MOSFET drain-source voltage (185 V AMR).
  • Operating frequency up to 300 kHz.
  • High-curren.
