Abstract
A power converting circuit including a converting circuit and a controller is provided. In an embodiemnt of the invention, the inductance of the converting circuit and the operation frequency of the controller can be adjusted according to the power required by the load and/or the size of the inductor current to effectively reduce the switching times and the switching loss of the switch in the converting circuit when the load is light. Accordingly, no matter the load is light or heavy, the efficiency of the power converting circuit can be maintained at a higher standard.
