1.3 Input Capacitor C9

The 47-uF, 25-V, tantalum capacitor C9 is added as the input capacitor in the EVM. The ESR of the tantalum capacitor is 0.12 Ω to damp the ringing of the input capacitor when the EVM is powered by a power supply with a long cable. The capacitor is not necessary and can be removed in a real application.
