Abstract

An apparatus and method of generating a drive signal for a switch in a switching converter having input terminals for applying an input voltage, output terminals for providing an output signal, and at least one inductive storage element coupled to the switch. The method includes sampling the output signal to provide a sampled output signal, and generating a pulsewidth modulated drive signal having a duty cycle that is dependent on the sampled output signal, wherein the output voltage is sampled at sampling times that are dependent on the duty cycle.
