Description
General part information
SRK1001 Series
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.
The control scheme of this IC is such that the SR MOSFET is switched on as soon as current starts flowing through its body diode, and then switched off as current approaches zero.
