I am trying to choose an output capacitor for the TPS6107 boost converter. My circuit will resemble the example from the datasheet.
Datasheet: http://www.ti.com/product/TPS61070/datasheet/abstract#SLVS5107171 Equations Used: http://www.ti.com/lit/an/slva372c/slva372c.pdf
I need to find the minimum output capacitance so I can select my capacitor.
I am using equation 12, on page 5, from the Equations Used link: Csub(out,min) = (Isub(out,max) x D)/ (fsub(s) x Delta Vsub(out))
I had to solve for the output voltage ripple, Delta Vsub(out), and the inductor ripple current, delta Isub(L), as well.
I have provided my calculations below, but I think my answer is wrong. I think i may have made a mistake with my units but i'm not sure.
