LM5163-Q1: The problem of inductance calculation in the application of LM5163 chip

??? ???

Part Number: LM5163-Q1
Other Parts Discussed in Thread: LM5163,

Hello, TI engineers

I found in the LM5163 specification books, inductance sense calculation formula, there are two unknown quantities, respectively inductance sense L, and inductance ripple current ΔIL；Two unknowns and one equation. How do I solve the inductance correctly；The calculation formula in the specification is as follows：

If you do not know how to calculate buck inductor, you can use Webench tool to get this value.
This chip LM5163-Q1's home page has the power design tool webench, you enter the design parameters.
The circuit will be generated.
