NAME
QFN TSSOP
IN 14 11 I Input of the Vcom buffer. If this pin is connected to GND, the Vcom buffer is disabled.
PGND 10, 11 7, 8 Power ground
REF 23 20 O Internal reference output typically 1.213 V
Supply pin of the positive, negative charge pump and Boost Converter Gate Drive Circuit.
SUP 12 9 I/O This pin needs to be connected to the output of the main boost converter and can’t be
connected to any other voltage rail.
SW 8, 9 5, 6 I Switch pin of the boost converter
Positive output voltage to drive the TFT gates with an adjustable falltime. This pin is
VGH 18 15 O
internally connected with a MOSFET switch to the positive charge pump input CPI.
VIN 7 4 I This is the input voltage pin of the device.
VCOM 13 10 O VCOM buffer output. Typically a 1-µF output capacitor is required on this pin.
