Abstract
An apparatus and method are disclosed for providing voltage control at a load of a buck converter. The buck converter is in a feedback loop so that a reference voltage determines a pulse width modulated (PWM) signal that is fed to the buck converter, and an output voltage of the buck converter is fed back to a PWM control circuit to maintain a value of the output voltage. The load at the buck converter provides event counters to a transient load current prediction circuit, which uses a curve fitting algorithm or other adaptive control algorithm to predict a change in current at the load. The transient load current prediction circuit then manipulates the reference voltage in accordance with the predicted change in current at the load.
