Our customer has some questions about LM3481.
I'm posting the questions for a customer:

(1)
The datasheet(SNVS346E) says ;
"The input capacitor should be capable of handling the rms current. Although the input capacitor is not as critical
in a SEPIC application, low values can cause impedance interactions. Therefore a good quality capacitor should
be chosen in the range of 100uF to 200uF."
How to decide the capacitance in the range of 100uF to 200uF with LM3481?
(Are there calculating formulas for the capacitance of INPUT/OUTPUT capacitors ?)
(2)
The datasheet(SNVS346E) says "Use capacitors with low ESR and ESL".
Specifically, what ohm is better for low ESR and ESL of the capacitor with LM3481?

thanks in advance.
