3.1.6.1 Sourcing VPP With ANALDO

With AM263P, it is possible to use the ANALDO output to connect to the VPP rail to source VPP without the need for an external LDO. By taking advantage of this added functionality, BOM costs can be reduced by removing the VPP LDO from the hardware design.

Figure 3-1 illustrates how the connection can be made. For boards that need to support AM263 devices, a path can be added to support the LDO as necessary.
