WebA flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters . WebFlyback Converter in Discontinuous Current Mode Generally, flyback transformers designed for both the types; CCM and DCM. It is decided by input voltage to apply and output side load situations. For working of CCM and DCM, the MOSFET driver IC requires a signal associated to the output voltage.
