The total power dissipated by the HVDD supply may be approximated using the equation:
Total HVDD Power
=
[
C
LOAD
HVDD
Reducing the H-loading, using only two of the outputs, and/or using a lower
HVDD
supply will reduce the power dissipation.
Actual HVDD power may be slightly higher than the calculated value because of stray capacitance inherent in the PCB layout/routing.
