8.3.1 Dynamic Voltage Positioning

This feature reduces the voltage undershoots/overshoots at load steps from light to heavy load and vice versa. It is active in power save mode and regulates the output voltage 1% higher than the nominal value. This provides more headroom for both the voltage drop at a load step, and the voltage increase at a load throw-off.
