I'm reviewing an existing TPS55340 design against the calculations in slva559.pdf. It's a great app note, thanks!
I'm wondering if there is a typo on Equation 24. The text states that the equation is for 10% ripple (0.1) but the denominator of the equation uses (0.01) that appears to be for 1% ripple. Is that a typo or am I missing something?
For reference, my existing design that works well has a 10 uF input capacitor and the result of Equation 24 shows the minimum input capacitance is 67 uF. 6.7 uF would make a lot more sense so that's why I'm asking.
Thanks,
John D
