Flyback power supply circuit
WebApr 12, 2006 · The DC-DC converter is a Flyback that uses a Zener diode clamp (VR3) on the MOSFET drain-node. It uses a 20 V, 4 A, standard Schottky diode (D1) for its output rectifier, and tantalum output capacitors (C7–C9). The frequency compensated (R11, C13) TL431 (U3) drives feedback through the opto-coupler (U2). WebThe Flyback transformer is similar to a buck-boost topology with an added transformer. The transformer provides isolation, step-up/step-down control using its winding turns ratio, …

WebA flyback controller IC controls the switching transistor (Ex: MOSFET) of a flyback converter via the GATE pin. When the switching MOSFET turns ON or closes, the input voltage is completely across the transformer (coupled inductors) so the inductor current increases linearly and thus the energy stored in the inductor gradually increases.
