Application Note 2076 for the LM3414 says that the peak inductor current should be 836mA if you use the example values provided in the document (Formula 5 on page 4) However when I plug in the provided values into the formula, I get 701mA.
Those sample values are:
- Vin(max) = 24.72
- Vf(min) = 18
- L(min) = 14.4
- f(sw) = 1000
- I(led) = 0.7
((24.72-18)*18)/(14.4*24.72*1000*2)+0.7 = .701
Am I missing something?
