ABSTRACT:
An improved active voltage positioning (AVP) implementation for a power supply for a microprocessor or the like includes an AVP circuit which is separated from the power supply error amplifier by a buffer amplifier having a parallel RC feedback circuit to controllably adjust the transient response. An AVP signal derived from an output load current sensing element provides an input to the buffer amplifier. A second input is provided by power supply reference voltage. A output of the buffer amplifier is connected as an input to the error amplifier to provide the AVP window. This permits separate adjustment of the transient behavior of the error loop and the AVP loop.
