Dynamic voltage positioning buck
WebAbstract: This paper proposes a lag-lead Active Voltage Positioning (AVP) technique that can be used in buck converters to minimize their output voltage transients during dynamic events, such as load pulses. The proposed technique is based on optimizing the output impedance of the converter across a wide range of frequencies, and therefore, output … WebThe NCP5392T provides up to a four--phase buck solution which combines differential voltage sensing, differential phase current sensing, and adaptive voltage positioning to provide accurately regulated power for Intel processors. It also receives power saving ... voltage even during a dynamic change in the VID setting during operation. Figure ...
