*_{The total power dissipated by the HVDD supply may be approximated using the equation:}
Total HVDD Power = [C_LOAD Ï« HVDD Ï« Pixel Frequency] Ï« HVDD Ï« Number of H-Outputs Used
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.
