PRODUCTION DATA.
Input and output capacitance improves the performance of the device. The actual capacitance should be optimized for the particular application. TI recommends to place the output capacitor in buck converter between SW_IN and AGND as close to the device as possible for local noise decoupling. Additional capacitance may be needed on the input to reduce voltage overshoot from exceeding the absolute maximum voltage of the device during heavy transient conditions. This is especially important during bench testing when long, inductive cables are used to connect the input of power switches in the evaluation board to the bench power-supply. TI recommends placing a high-value electrolytic capacitor on the output pin when large transient currents are expected on the output.
