Flyback synchronous rectification
WebSynchronous Rectification The secondary side of the forward circuit typically requires two freewheeling diodes for the excitation inductance and the output inductance. These diodes lead to considerable losses during the freewheeling process under high-current outputs. WebThe UCC24610EVM-563 is a 25W, 5V off-line DCM Flyback converter with secondary side synchronous rectification controlled by the UCC24610. The primary side control is provided by the UCC28610 Green-Mode Flyback Controller.

WebThe MP6919 is a fast turn-off, intelligent rectifier for flyback converters that integrates a 100V MOSFET. It offers higher efficiency and power density than a diode rectifier. The chip regulates the forward voltage drop of the internal power switch to 40mV (1), and turns off before the drain-source voltage reverses.
