Based on the forma in datasheet, the inductor selected should be 48uH for below application.
But it’s far away from the recommended indutor in datasheet, which is 4.7uH.
Why one is right?
Application: Vin = 6~20V, Vout = 12V, Iout = 0.6A, fsw = 500KHz

Hi Liping,
A 4.7uH inductor is good enough. We can evaluate after seeing the hardware testing performance.
Best,

Thanks Fox! Can you explain a little more about why datasheet formula come out a different result?
