The only problem with this chip, is that the switching frequency is fixed, that may cause some problems when selecting Inductors, luckily, after calculation I can source pretty good inductors based on the fixed frequency, so in the end I chose the MP2491CGQB-Z chip
EN Current Calculation:
R_Pullup +3kOhm (internal pullup) = (24V-7V)/I_EN (7Volt is the internal Zener Diode)
...
In this case, R_Pullup=220kR, so I_EN=62.7uA, smaller than the 100uA, which is good.
Inductor
From the data sheet the design requirements of the inductors is that:
