FUNCTION
Amplifier Ground
Operational Amplifier Supply Input. Connect to V MAIN (Figure 2) and bypass to BGND with a 1 μF or
greater ceramic capacitor.
Adjustable Sink-Current Output. OUT connects to the resistive voltage-divider at the op amp input POS
(between BOOST and GND) that determines the VCOM output voltage. I OUT lowers the divider voltage by
a programmable amount.
Operational Amplifier Noninverting Input
Operational Amplifier Inverting Input
Operational Amplifier Output
Shutdown Control Input. Pull SHDN low to disable the step-up regulator. The VCOM calibrator, op amp,
and scan driver functions remain enabled.
Step-Up Regulator Supply Input. Bypass IN to AGND (pin 34) with a 1μF or greater ceramic capacitor.
Switching Node. Connect inductor/catch diode here and minimize trace area for lowest EMI.
Power Ground. Source connection of the internal step-up regulator power switch.
Feedback Input. Reference voltage is 1.24V nominal. Connect external resistor-divider
midpoint here and minimize trace area. Set V OUT according to: V OUT = 1.24V (1 + R1/R2).
Compensation Input for Error Amplifier. Connect a series RC from COMP to AGND. Typical values are
180k and 470pF.
Ground
Gate-Off Supply. GOFF is the negative supply voltage for the CKV, CKVB, and STVP high-voltage driver
outputs. Bypass to PGND with a minimum of 0.1μF ceramic capacitor.
Gate-On Supply. GON is the positive supply voltage for the CKV, CKVB, and STVP high-voltage driver
outputs. Bypass to V MAIN or PGND with a minimum of 0.1μF ceramic capacitor.
Exposed Backside Pad. Connect to the analog ground plane through multiple vias to enhance thermal
performance.
