PV3 to AGND with a 2.2 F F ceramic capacitor as close as possible to the IC. PV3 is high impedance
during shutdown. Connect PV3 to PV1, PV2, and PV5.
Supply Voltage Input. Connect PV2 to PV1.
Supply Voltage Input for the Step-Up Converter. The input voltage range is 2.7V to 5.5V. Bypass PV5
to PGND3 with a 1 F F ceramic capacitor as close as possible to the IC. PV5 is high impedance during
shutdown. Connect PV5 to PV1, PV2, and PV3.
Supply Voltage Input for LDO3. The input voltage range is 1.7V to 5.5V. Bypass PV4 to AGND with a
2.2 F F ceramic capacitor as close as possible to the IC. PV4 is high impedance during shutdown. If
PV4 is not used separately, connect PV4 to PV1.
Supply Voltage Input for Charge-Pump Circuitry. The input voltage range is 2.7V to 5.5V. Bypass PV1 to
PGND1 and PGND2 with a 4.7 F F to 10 F F ceramic capacitor as close as possible to the IC. PV1 is high
impedance during shutdown. Connect PV1 to PV2, PV3, and PV5.
