WebThe UCC1889 controller is optimized for use as an off-line, low power, low voltage, regulated bias supply. The unique circuit topology utilized in this device can be visualized as two cascaded flyback converters, each operating in the discontinuous mode, and both driven from a single external power switch. WebThe terms flyback or kickback originate from the induced voltage reversal that occurs when the supply current is interrupted. The reversed induced voltage (s) tries to create (induce) a current flow. The open switch prevents current from flowing through the power supply.

Web2 aug. 2024 · A flyback transformer is made up of a primary and secondary inductive winding on a core material. In some cases, a flyback transformer is also referred to as a coupled inductor. Like regular transformers, the flyback transformer converts primary voltage to secondary voltage through the ratio of the winding and the core material.
