Component values used for the Built-in Switching Regulator

Question: What is the component values used for the Built-in Switching Regulator?

 

Answer:

  

The component values for the schematic are below. 

CIN = 1 μF, X7R

L = 47 μH, +/-10%, 1.5 A rated saturation current

Rsense = 0.5 Ω, 0.1W

Rfb1 = 2 KΩ, 1%, 0.1W

Rfb2 = 698 Ω, 1%, 0.1W

Rcomp = 20 KΩ, 5% or better, 0.1W

Ccomp = 2200 pF,

C1 = 10 μF, X7R with ESR >= 0.1Ω
