Active voltage positioning (AVP), which refers to setting the power supply output voltage at a point that is dependent on the load current, is discussed.
Active voltage positioning
Power supply performance, especially transient response, is key to meeting today’s demands for low voltage, high current microprocessor power. In an effort to minimize the voltage deviation during a load step, a technique that has recently been named “active voltage positioning” is generating substantial interest and gaining popularity in the portable computer market. The benefits include lower peak-to-peak output voltage deviation for ...
