One of the most influential components on the thermal performance of a package is board design. In order to take full advantage of the heat
dissipating abilities of the PowerPAD packages, a board must be used that acts similar to a heat sink and allows for the use of the exposed (and
solderable), deep downset pad. See Appendix A of the PowerPAD Thermally Enhanced Package application note, TI literature number SLMA002
and the Thermal Design of the PowerPad PCB Layout section of the System Design Considerations for True Digital Audio Power Amplifiers
application note, TI literature number SLAA117.

Connect LDROUTA to PVDDA2 and connect LDROUTB to PVDDB2. Under this condition H-Bridge forward on-state resistance is increased.
This increases internal power dissipation. Maximum output power may need to be reduced to meet thermal conditions.
