WebMay 8, 2024 · We covered flyback design trade-offs and power-stage equations for a CCM flyback in Power Tips #76: Flyback converter design considerations and Power Tips #77: Designing a CCM flyback converter. CCM operation is best suited for medium- to high-power applications, but if you have a low-power application that could use a DCM … WebDCM pushes the RHPZ to higher frequencies, making the loop easier to compensate, and therefore offering faster transient response than CCM. Furthermore, when working with duty cycles above 0.5, subharmonic oscillation may occur in CCM flyback converters, which means slope compensation is required.
