Hello,
I have a question on calculating the Inductor value for the LM61480.
Equations 5 and 6 in the datasheet don’t seem to correlate to each other. Can you clarify what equation 6 is for?
My variables are Vin = 12V; Vout = 9.5V; Fsw = 400k; K = 0.3; Iout(MAX) = 8A (actually 6A, but says to use max of part). This gives me an L = 2.06uH, which makes sense.
Equation 6 says L > 5uH. What is Irated? 8A?. This is why eq 6 doesn’t make sense to me.
