APPLICATION INFORMATION
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
underneath the integrated circuit package must be
soldered to the printed-circuit board.
