1.5.11.3.1 PVDD Only (12 V to 45 V)

This power mode is the default setup when the board is tested and shipped. The user can connect any valid supply voltage to J1 and the onboard LDOs will generate the required non-PVDD voltages. PVDD itself always connects directly to the TPA3223 PVDD pins. Setup for this mode is the same as described in Quick Start (BTL MODE).
