Pin Description

FUNCTION

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 VOUT

according to: VOUT = 1.235V (1 + R1/R2) (Figure 1).

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.

High-Voltage-Driver Logic-Level Inputs

Level-Shifter High-Voltage Outputs

High-Voltage-Driver Logic-Level Inputs

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.

Amplifier Ground

Op Amp and Internal VL Linear Regulator Supply Input. Bypass SUP to BGND with a 0.1µF capacitor.

Op Amp Noninverting Input

Op Amp Inverting Input

Op Amp Output

Shutdown Control Input. Pull SHDN low to turn off the DC-DC converter and high-voltage drivers only

(VL and op amp remain on).

Supply Pin. Bypass to AGND with a minimum 0.1µF ceramic capacitor.

Switching Node. Connect inductor/catch diode here and minimize trace area for lowest EMI.
