Adaptive Voltage Positioning
Adaptive voltage positioning is needed to reduce the output voltage deviations during load transients and the power
dissipation of the load when it is drawing maximum current. The circuitry related to voltage positioning is shown in
Figure 8. Resistor R
voltage. An internal current source whose value is programmed by the same external resistor that programs the
oscillator frequency pumps current into the FB pin. The error amp forces the converter’s output voltage lower to
maintain a balance at its inputs. R
DAC voltage.
