WebFlyback Converter This model shows how a flyback converter can step-up a 5V DC source into a 15V DC regulated supply. The voltage is increased by creating a time-varying … WebThis means there are two feedback loops: one that monitors the output voltage, and a faster loop that monitors the current through the inductor. Whether it is a forward, buck, boost or a flyback topology, the current-mode controller will require monitoring of both loops for standard operation.
