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. WebCircuit Description Circuit Graph The 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, and multi-output capabilities. little bug drawing
