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.
Open drain output indicating when all outputs Vo1, Vo2, Vo3 are within 10% of their
nominal output voltage. The output goes low when one of the outputs falls below 10%
of their nominal output voltage.
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
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 needs to be connected to GND.
Positive terminal for the charge pump flying capacitor. If the device runs in voltage
doubler mode, this pin needs to be left open.
Supply pin of the positive, negative charge pump, boost converter, and gate drive
circuit. This pin needs to 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 power ground pins
