FUNCTION
Analog GND
Open-Drain HVS Mode Output. For details, see the HVS Mode section.
Error-Amplifier Output. Connect a series RC network from COMP to AGND for compensation.
Step-Up Regulator Feedback Input. Connect FB to the center of a resistive voltage-divider between the step-
up regulator output and AGND. Place the resistive voltage-divider within 5mm of FB. For details, see the
Output-Voltage Selection section.
Internal High-Voltage Switch Common Terminal. GON common terminal between the high-side p-channel
MOSFET and back-to-back p-channel MOSFET. GON is internally pulled to PGND by a 100k ? resistor in
shutdown.
High-Voltage Switch Drain. Drain of the internal low-side, back-to-back p-channel MOSFET.
Positive Charge-Pump Regulator Feedback Input. Connect FBP to the center of a resistive voltage-divider
between POUT and AGND. Place the resistive voltage-divider within 5mm of FBP. For details, see the Output-
Voltage Selection section.
Positive Charge-Pump Output and High-Voltage Switch Source Input
Positive Terminal of Flying Capacitor C2
Negative Terminal of Flying Capacitor C2
