Description

General part information

SRK1000 Series

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 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 it is then switched off as current approaches zero.
