    摘要: An apparatus and method for regulating a voltage to a load to compensate for one or more parasitic impedances. A first amplifier measures the voltage drop due to a first parasitic impedance, and a second amplifier measures the voltage drop due to a second parasitic impedance. An offset generator sums the first and second voltage drops with a reference voltage, and drives a DC-to-DC converter to produce an input voltage matching the summed voltages. Accordingly, the voltage at a load between the parasitic impedances matches the reference voltage. The load may be, for example, a computer microprocessor or central processing unit.

    摘要: 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.

    摘要: Systems and methods for regulating a switching converter are disclosed. One embodiment of the present invention relates to a power supply system that includes a switching converter that provides an output voltage by alternately turning on and off a high-side transistor and a low-side transistor both coupled to an output inductor through a switching node. The switching converter includes a drive circuit that regulates the output voltage based on a feedback signal. The power supply system also includes a simulated output generator that generates and provides the drive circuit with a simulated inductor waveform as the feedback signal based on a low-side output waveform of the low-side transistor measured at the switching node during off-times of the switching converter.
