Table 1 - Voltage Identification (VID)
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
FB
is connected between the Error Amplifier’s inverting input pin FB and the converter’s output
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 amplifier forces the converter’s output voltage lower to
maintain a balance at its inputs. R
FB
is selected to program the desired amount of fixed offset voltage below the
DAC voltage.
The voltage at the VDRP pin is a buffered version of the share bus and represents the sum of the DAC voltage and
the average inductor current of all the phases. The VDRP pin is connected to the FB pin through the resistor R
DRP
.
Since the Error Amplifier will force the loop to maintain FB to be equal to the VDAC reference voltage, an additional
current will flow into the FB pin equal to (VDRP-VDAC) / R
DRP
. When the load current increases, the adaptive
positioning voltage increases accordingly. More current flows through the feedback resistor R
FB
, and makes the
output voltage lower proportional to the load current. The positioning voltage can be programmed by the resistor
R
DRP
so that the droop impedance produces the desired converter output impedance. The offset and slope of the
converter output impedance are referenced to and therefore independent of the VDAC voltage.
