    I having some trouble determining the inductor value for a buck converter. Here are the design specifications:
    Vin: 12.0V
    Vout: 5.0V
    Regulation: +/- 25mV
    Load: 20W
    Switching Freq: 200 kHz

    Here is my work thus far:
    R = \frac{5^{2}}{20} = 1.25Ω
    D = Vo/Vin = 5/12 = 0.416667
    I_L = Vo/R = 5/1.25 = 4A

    How do I find ΔIL so I can use the following equation to find my L value?
    ΔIL = -(1/L)*Vout * (1-D) * T
