APPLICATION INFORMATION
SLVS726 – JANUARY 2007
Figure 10 shows the schematic diagram for a typical TPS54610 application. The TPS54610 (U1) can provide
greater than 6 A of output current at a nominal output voltage of 3.3 V. For proper thermal performance, the
exposed thermal PowerPAD under the integrated circuit package must be soldered to the printed-circuit board.
