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. WebSynchronous Flyback Controller The NCP4302 is a full featured controller and driver that provide all the control and protection functions necessary for implementing a …
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. WebA flyback converter is provided that dynamically adjusts a drain threshold voltage for a current cycle of a synchronous rectifier switch transistor based upon operating conditions in a previous cycle of the synchronous rectifier switch transistor. A differential amplifier drives a gate voltage of the synchronous rectifier switch transistor during an on-time of the …
