According to an embodiment, a method of operating a switching power supply includes applying a periodic switching signal to a first switch that is coupled to an output node, detecting an offset delay between applying the periodic switching signal and a change in voltage of the output node, calculating a corrected midpoint of a half phase of the periodic switching signal based on the offset delay, generating a sampling pulse based on the corrected midpoint, and sampling a current at the output node according to the sampling pulse.

Semiconductor device and method for controlling a semiconductor device

A switching control circuit for a DC-DC converter comprises an input terminal to receive input signals and an output terminal to couple the switching control circuit to a switch of the DC-DC converter. A quasi-static supply path is coupled to the input terminal to receive first signals based on the input signals and coupled to the output terminal to provide output signals to the output terminal based on the input signals. A dynamic supply path is coupled to the input terminal to receive second signals based on the input signals in-phase with the first signals and coupled to the output terminal to provide output signals to the output terminal based on the input signals.
