9.2 Typical Application

Figure 10 shows the schematic diagram for a typical TPS54310 application. The TPS54310 (U1) can provide up to 3 A of output current at a nominal output voltage of 3.3 V. For proper thermal performance, the power pad underneath the TPS54310 integrated circuit needs to be soldered well to the printed-circuit board.
