Adaptive Voltage Positioning
Adaptive voltage positioning is implemented needed to reduce the output voltage deviations during load transients
and the power dissipation of the load at heavy load. The circuitry related to voltage positioning is shown in Figure 9.
The output voltage is set by the reference voltage VSETPT at the positive input to the error amplifier. This reference
voltage can be programmed to have a constant DC offset bellow the VDAC by connecting RSETPT between VDAC
and VSETPT. The IVSETPT is controlled by the ROSC as shown in Figure 10.
