11.1 Power Supplies

The TPA3220 device requires a single external power supply for proper operation. A high-voltage supply, PVDD, is required to power the output stage of the speaker amplifier and its associated circuitry. PVDD can be used to supply an internal LDO to supply 5 V to AVDD and GVDD (connect VDD to PVDD).

Additionally, in LDO bypass mode an external power supply should be connected to VDD, AVDD and GVDD to power the gate-drive and other internal digital and analog circuit blocks in the device.

The allowable voltage range for both the PVDD and VDD/AVDD/GVDD supplies are listed in the Recommended Operating Conditions table. Ensure both the PVDD and the VDD/AVDD/GVDD supplies can deliver more current than listed in the Electrical Characteristics table.
