Ordering & quality Support & training 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.
