SSD1820A and SSD1821 IC work from 2X to 5X and 2X to 6X DC-DC converter respectively. For the capactior connections,
please refer to below circuit diagrams. Note that if the capacitor connection does not match with the software setting of DC-DC
Converter Factor (0x64~0x67), abnormal current consumption will be observed.
