LOW LOSS SWITCHING MODE POWER CONVERTER OPERATING IN BOTH CCM AND DCM

摘要

A switching mode power converter (11) has an input (12) and an output (13). The switching mode power converter may be configured to transition between a continuous conduction mode (CCM) at a first load level and a discontinuous conduction mode (DCM) at a second load level, where the second load level is lower than the first load level. A control circuit (14) may be connected to the switching mode power converter (11), wherein the control circuit (14) is configured to adjust the switching frequency of the switching mode power converter (11) during the transition between the continuous conduction mode and the discontinuous conduction mode in accordance with maintaining low voltage deviation with respect to a reference voltage .
