Figure 10 shows the schematic diagram for a typical TPS54617 application. The TPS54617 (U1) can provide up
to 6A of output current at a nominal output voltage of 1.8 V. For proper thermal performance, the exposed
thermal PowerPAD underneath the integrated circuit, TPS54617, package must be soldered to the printed-circuit
board.
Analog and power grounds are ties at the pad under the package of the IC

capacitor that provides high-frequency decoupling of
the TPS54617 from the input supply. C1, C2 and C12
must be located as close as possible to the device.
Input ripple current is shared among C1, C2 and C12.
