No Connection. Not internally connected.
Power Ground. Source connection of the internal step-up regulator power switch.
Feedback Pin. Connect external resistor-divider tap here and minimize trace area. Set V
according to: V
Ground
Gate-On Supply. GON1 is the positive supply for the Y1–Y6 level-shifter circuitry. Bypass to AGND
with a minimum 0.1µF ceramic capacitor.
Gate-Off Supply. GOFF is the negative supply voltage for the Y1–Y8 high-voltage driver outputs.
Bypass to AGND with a minimum 0.1µF ceramic capacitor.

Gate-On Supply. GON2 is the positive supply for the Y7 and Y8 level-shifter circuitry. Bypass to AGND
with a minimum 0.1µF ceramic capacitor.
Ground. Internally connected to pin 5.
Compensation Pin for Error Amplifier. Connect a series RC from this pin to AGND. Typical values are
100kΩ and 220pF.
4V On-Chip Regulator Output. This regulator powers internal analog circuitry for the boost and op
amp. Bypass VL to AGND with a 0.22µF or greater ceramic capacitor.
