Hello
There is a problem when I am solving DUTY, Ton, and Inductance Value(L1) for Inductor selection.
I substituted the table 11 values in the ADP5072 Datasheet into the Inductor selection equation(in the ADP5072 Datasheet).
Table 11 values are Vin, Vpos, Iload1, and Frequency.
So, I got the L1 value from the equation.
But, The L1 value from the equation was not the L1 value from Table 11.
Please pay attention to Table 11 in the attached picture.
For example, Let's substitute the values of Vin = 5 V, Vpos = 9, Iload = 140 mA, Frequency = 1.2 MHz into the Inductor selection equation.
The picture above is the Inductor selection equation.
When Vdiode is as 0.2V, Duty = 0.45652% , Ton = 0.38043x10^-6, L1 = 24.61uH.
But, the L1 value of Table 11 is 3.3uH.
I want to know if I'm wrong with the calculation or if the equation is wrong.
Regards
Haks
