Abstract
A power supply system delivers current to a load at a corresponding load voltage. The power supply system includes multiple power converter phases. Each power conversion phase comprises a phase switch and a phase inductor. In one embodiment, activation of a corresponding phase switch (e.g., a field effect transistor such as a MOSFET) electrically couples a voltage input (e.g., Vin) to an inductor electrically coupled to deliver current to a load. A controller (e.g., a processor device) associated with the power supply system is configured to monitor the load and/or a change in the current delivered to the load. Based on the monitoring, the controller modifies a relative timing of an initiation and duration of on-times of the phase switches in order to alter a rate-of-change of the current delivered by the power supply system.
