Abstract
A switched mode power supply may include circuitry configured to output a bias signal that turns off and on switching circuitry of the switched mode power supply. The circuitry may wait for a first time period determined by the bias signal, and output the bias signal to turn off the switching circuitry when the time period expires. In addition or alternatively, the circuitry may begin waiting for a second time period when the bias signal turns off the switching circuitry. The circuitry may turn on the switching circuitry either when energy in inductive storage circuitry is depleted or when the second time period expires.
