is it necessary to connect decoupling capacitors on the inputs of the PMIC if the corresponding outputs are not used?
E.g. if I don't use the SW1A buck converter, do I have to put a decoupling capacitor at SW1AIN?
And if yes, do I have to connect it to a voltage rail or can it let be floating?
The same applies to unused LDOs (VGENs) and VINREFDDR and VHALF. What should I do with the inputs and outputs if they are not used?
Thank you very much in advance.
