In the datasheet, there are some steps in the inductor calculation that appear to be missing or unclear.
For equation 4 on page 13, I put in these values for the example:
Vbat = 0.9V, Vout - 3.3V, ∂I(L) = 40%, f = 1.2MHz, I(o) = 75mA. Using those values, I get L = 1.36uH. The text says it should be 4uH. What did I do wrong?
My application is similar: 3.3V Vout, 1.6V Vin(min), I(o) = 150mA (peak). I want efficiency to be 85%+ but small area. Is this the best part TI has for this application?
