NAME

Input voltage pin of the device
Enable pin of the device. This pin should be terminated and not be left floating. A logic
high enables the device and a logic low shuts down the device.
Compensation pin for the main boost converter. A small capacitor is connected to this
pin.
Positive input terminal of the VCOM buffer. When the VCOM buffer is not used, this
terminal can be connected to GND to reduce the overall quiescent current of the IC.
Enable pin of the linear regulator controller. This pin should be terminated and not be
left floating. Logic high enables the regulator and a logic low puts the regulator in
shutdown.
Positive terminal of the charge pump flying capacitor
Negative terminal of the charge pump flying capacitor
External charge pump driver
Feedback pin of negative charge pump
Internal reference output typically 1.23 V
Feedback pin of the linear regulator controller. The linear regulator controller is set to a
fixed output voltage of 3.3 V or 3.0 V depending on the version.
Base drive output for the external transistor
Ground
Power ground
VCOM buffer output
Feedback pin of positive charge pump
Positive charge pump output
Negative terminal of the charge pump flying capacitor and charge pump MODE pin. If
the flying capacitor is connected to this pin, the converter operates in a voltage tripler
mode. If the charge pump needs to operate in a voltage doubler mode, the flying
capacitor is removed and the C2-/MODE pin should be connected to GND.
Positive terminal for the charge pump flying capacitor. If the device runs in voltage
doubler mode, this pin should be left open.
Supply pin of the positive, negative charge pump, boost converter gate drive circuit,
and VCOM buffer. This pin should be connected to the output of the main boost
converter and cannot be connected to any other voltage source. For performance
reasons, it is not recommended for a bypass capacitor to be connected directly to this
pin.
Feedback pin of the boost converter
Switch pin of the boost converter
The PowerPad or exposed thermal die needs to be connected to the power ground
pins (PGND)
