10.1 Layout Guidelines

The TPS65233-1 is designed to layout in a 2-layer PCB. Figure 32 shows the recommended layout practice. It is critical to make sure the GND of the input capacitor, output capacitor, and boost converter are connected at one point on the same layer as shown below. PGND and AGND are in different regions and are connected to the thermal pad. Other components are connected to AGND.
