Pattern Diagram for Voltage Setting
The following figures are the pattern diagram of voltage setting for the HD66787 and the voltage
waveforms.
VGH (+9 ~ +16.5V)

Pattern diagram for voltage setting
Note 1) Voltage drop occurs in relation to set voltage for each DDVDH, VGH, VGL, VCL output depending
on current consumption required for each output. (DDVDH+VREG1OUT) > 0.5V and
(VcomL – VCL) > 0.5V show the relationship in relation to the actual voltage. When AC frequency of
Vcom1 and Vcom2 is high (e.g. alternation occurs by line), current consumption is also large. In this
case, check voltage before use.
