FUNCTION
Level-Shifter Logic-Level Inputs
Start-Pulse, Level-Shifter Logic-Level Input
Gate-Shading Discharge for CKH2, CKH4, and CKH6
VGL Voltage Output
Level-Shifter Outputs
Start-Pulse Level-Shifter Output
Gate-Off Supply. VGL is the negative supply voltage for the STH, CKH1–CKH6, and VGLC high-volt-
age driver outputs. Bypass to PGND with a minimum of 0.1 F F ceramic capacitor.
Gate-On Supply. GHON is the positive supply voltage for the STH, CKH1–CKH6, and VGLC high-
voltage scan-driver outputs. Bypass to PGND with a minimum of 0.1 F F ceramic capacitor.
Gate-Shading Discharge for CKH1, CKH3, and CKH5
Operational Amplifier Output
Operational Amplifier Noninverting Input
Operational Amplifier Supply Input. Connect to V MAIN (Figure 1) and bypass to AGND with a 0.1 F F or
greater ceramic capacitor.
Compensation for Error Amplifier. Connect a series RC from this pin to AGND. Typical values are
56k I and 1000pF.
Step-Up Regulator Feedback. Reference voltage is 1.24V nominal. Connect the midpoint of an exter-
nal resistor-divider to FB and minimize trace area. Set V MAIN according to V MAIN = 1.24V (1 + R1/R2).
