2, and Figure 3 show the board layout for the TPS62233EVM-574 printed-circuit board. The nodes with high- switching frequencies and currents are kept as short as possible to minimize trace inductance. High- impedance inputs to the TPS62233, such as the Vout pin, have traces that are shielded by ground traces and planes. -
