Hello Team

I'd like to concfirm validity of inductor selection design.

Our circuit requirement

Vin : 19V

Vout : 5.15V

Iout : 150mA (max)

I calculated inductor inductance constant with eq.(7) in the datasheet (Revision A Dec, 2022)

Do the parameters using calculation follow design guidline?

VIN=19V, VOUT=5.15V, Fsw=1.055MHz, K by Iout_max = 0.2

Then, calculation result is 17.8uH

Also, are there any design guidelines for the current flowing into the Swichng Coil immediately after power on?

*VIN and EN are used short-circuited.

Best Regard
