The LMR50410-Q1 device requires a high frequency input decoupling capacitor or capacitor. 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.
