Description
General part information
EVLSRK1004A Series
The EVLSRK1004A, EVLSRK1004B, EVLSRK1004C, and EVLSRK1004D are demonstration boards, designed for evaluation of the SRK1004x synchronous rectification controller.
The SRK1004 is a controller intended for secondary side synchronous rectification (SR) in a Non-Complementary Active Clamp Flyback converter. It provides a gate-drive output suitable for N-channel logic-level or standard level 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.
