摘要
A controller for a DC to DC converter, comprising first and second electrically controlled switches and an inductor, wherein placing the first switch in a low impedance state causes a current flow in a first direction through the inductor to increase, and placing the second switch in a low impedance state causes the current flow in the first direction to decrease. The controller can operate a DC to DC converter in a first mode when a current taken by a load supplied by the converter is above a first current threshold, and in a low power mode when the current taken by the load is below the first current threshold, wherein the controller uses information about a switching time of the first switch in the first mode to control a switching time of the first switch in the low power mode.
