The evaluation module provides an external pullup resistor of 10 k
(R8), test
point TP1 that can be tied to an external 3.3-V or 5-V source and test point TP2
to monitor the power good signal.

Synchronous Low-Side FET
The TPS54350EVM-235 is provisioned with a external low-side FET for
operation as a synchronous buck regulator. If desired, an external catch diode
may be used in place of the FET. The pad for the diode is located on the back
side of the PCB. Verify that the inductor is properly sized for operation without
the low-side FET. The minimum value for the inductor when operating in this
mode is given by the following equation.
