Capacitor selectionFour 10µF ceramic capacitors in parallel are used at the output.Figure 5.9: Worksheet for 7.2V converter, step 2.From the second step, the value <strong>of</strong> the maximum inductor current is found to be 1.53A.This current is acceptable for the switch.<strong>Design</strong> <strong>of</strong> other componentsR comp <strong>and</strong> C comp :Using V in = 3.7, C out = 40µF, L = 6.8µH, I outMax = 0.42A. in the formulas from theTPS61087 datasheet, we findR comp = 110V inV out C outLI outMax= 41kΩ,C comp =V out C out7.5I outMax R comp= 2.126nF.The real components chosen have the values C comp = 2.2nF <strong>and</strong> R comp = 41kΩ.C ss60
