Flyback feedback circuit
http://boginjr.com/electronics/hv/flyback-driver-1/ WebOne of the most important factors in the design of a flyback converter power supply is the design of the transformer. The main advantages of the flyback circuit are cost, simplicity and the ease of adding multiple outputs. Flyback topologies are practical and lowest cost for systems up to 100W. Flyback transformer design is a somewhat iterative

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.
