Abstract
An apparatus includes a filter to receive a signal indicating a magnitude of current supplied by an output voltage to power a dynamic load. The filter produces a filtered signal from the received signal. A reference voltage generator generates a target setpoint voltage based on the filtered signal. The target setpoint voltage is used to control (such as regulate) a magnitude of the output voltage. The apparatus further includes a filter controller to dynamically change operational settings of the filter. For example, the filter controller reduces the bandwidth of filtering the signal in response to detecting that: i) the magnitude of the output voltage falls below an output voltage threshold value, and ii) the magnitude of a received VID value is greater than a VID threshold value.
