Adaptive synchronous rectifier controller in 6pin SOT23

ST has introduced a pair of autonomous secondary-side synchronous-rectification controllers for fly-back converters, suitable for quasi-resonant and continuous-discontinuous conduction fixed frequency circuits up to 300kHz. Called SRK1000A and SRK1000B, they include adaptive switching logic “such that the synchronous rectifier mosfet is switched on as soon as current starts flowing through its body diode and it is then switched ...
