Good Afternoon,
I'm looking to choose an Inductor to be used with this part. I'm currently looking at the A variant (400kHz fsw).
Using WBench, an inductor of 15uH has been chosen; but using the formula in the datasheet it recommends a minimum of 220uH (roughly).
Using 0.3 for the constant k. Range of the input is between 10V and 16.8V; 16.8V used in the formula. The output being 3V3 @ 100mA.
Which value would you recommend using?
values summarised as:
Vin = 16.8V
Vout = 3.3V
K = 0.3
Fsw = 400kHz
Imax = 0.1A
Many Thanks
