UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The TPS560430 device requires high frequency input decoupling capacitor(s). The typical recommended value for the high frequency decoupling capacitor is 2.2 µF or higher. A high-quality ceramic type X5R or X7R with sufficiency voltage rating is recommended. The voltage rating must be greater than the maximum input voltage. To compensate the derating of ceramic capacitors, a voltage rating of twice the maximum input voltage is recommended. For this design, one 2.2-µF, X7R dielectric capacitor rated for 50 V is used for the input decoupling capacitor. The equivalent series resistance (ESR) is approximately 10 mΩ, and the current rating is 1 A. Include a capacitor with a value of 0.1 µF for high-frequency filtering and place it as close as possible to the device pins.
