LM60430 datasheet P19 is described that "a minimum of 10µF of ceramic capacitance is required", but the other EVM and reference schematic are used 4.7μF (and 220nF×2).
Please let me know about the background for Cin has established more than 10μF.
I think that 4.7μF is OK if matched input and ripple condition.
