Abstract
A DC-to-DC converter includes first and second switches connected to each other at a node and biased by PWM pulses. A timing module determines a first time difference between a first edge of a first signal at the node and a first edge of a second signal at a control terminal of the first switch, and a second time difference between a second edge of the first signal and a second edge of the second signal. The first and second edges of the second signal correspond to first and second edges of one of the PWM pulses, respectively. A delay module delays the first and second edges of the second signal based on the first and second time differences, respectively. The delay module delays an edge of one of the PWM pulses based on an amount of change in a voltage output by a charge pump.
