VCORE accuracy
Starting from Equation 7 and Equation 9, the programmed output voltage is given by:
Equation 23
●
VDAC is the internal reference voltage, i.e. the digital-to-analog converter output
programmed by the 7 VIDs;
●
GD is the droop gain, given by Equation 8;
●
GSNS is the current sensing filter attenuation. This element is lower than 1 if there is an
NTC thermal compensation network, typically used in DCR current sensing technique;
●
RSNS is the current sensing element, i.e. the inductor DCR or the precision resistor;
The statistical variation of the output voltage is given by the following equation:
Equation 24
●
δV
DAC is the internal reference voltage error, lower than 0.7% of the programmed VID
●
δG
D/GD and δGSNS/GSNS are the statistical error of the droop gain and NTC network, if
used. This two elements are only influenced by external components;
●
δR
SNS is the current sensing element (inductor's DCR or precision resistor) variation
due to its accuracy;
●
δV
OFFSET < 2.5 mV is the PM6652 integrator maximum offset.
Based on Equation 7 the droop gain statistical error is:
Equation 25
