WebAug 31, 2024 · This is because in DCM, the converter is a power regulator; in CCM the converter is a voltage regulator. Low output powers therefore require low duty cycle and, the point you may be missing is that it is impossible to force CCM on very light loads. WebContinuous Current Mode (CCM) and Discontinuous Current Mode (DCM) are the names of operation modes of switching power supplies, such as DC/DC and AC/DC. The CCM and DCM are divided by the flow direction of the coil current.
