Abstract
An apparatus includes a controller that monitors an error voltage indicating a difference between an output voltage and a setpoint voltage. Based on the monitored error voltage, the controller generates modulation adjustment signals including a frequency adjustment signal and an ON-time adjustment signal. The controller generates a pulse width modulation signal of a first power supply phase in accordance with both the frequency modulation adjustment signal and the ON-time adjustment signal.
