Abstract

A controller circuit for controlling a switching-mode power supply (SMPS) is configured to receive a load control signal indicating an on state when a load is to be coupled to the SMPS and an off state when the load is not to be coupled to the SMPS. In response to the load control signal transitioning from the on state to the off state, the controller circuit is configured to generate a first measured input voltage. In response to the load control signal transitioning from the off state to the on state, the controller circuit is configured to generate a second measured input voltage. The controller circuit is configured to drive a compensation voltage at a compensation element using the first measured input voltage and the second measured input voltage and selectively switch the SMPS using the compensation voltage after driving the compensation voltage.
