Abstract
An apparatus includes a controller a current mode controller that produces an output voltage by supplying output current from at least one power supply phase of a power supply to power a load. The controller produces an error current signal based on a difference between a magnitude of the output current supplied from the power supply to a load and a phase current setpoint. Based on a magnitude of the error current signal, control a pulse width setting of a pulse width modulation signal controlling the at least one power supply phase. The controller varies a leading edge and a falling edge of a pulse width ON-time of the pulse width modulation signal over each of multiple control cycles depending on variations in the magnitude of the pulse width setting.
