Flyback calculation

Webadopted in UCC28600 flyback design. 2. Small Signal Model of DCM Flyback . Because UCC28600 is a quasi-resonant flyback, it operates in DCM mode; therefore, to design feedback network and calculate relevant parameter, small signal model of DCM flyback is needed. The total small signal model is composed of the following functions: WebThe design of a DCM flyback is an iterative process; some initial assumptions, such as switching frequency, inductance or turn ratios may change based on later calculations, like power dissipations. But remain diligent – an optimized DCM flyback design can provide a low-power, compact and low-cost solution.
