SRK1001 Datasheet (STMicroelectronics) - Adaptive synchronous rectification controller

SRK1001, Adaptive synchronous rectification controller

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.
