PRODUCTION DATA
The coupling capacitors Cs isolate the input from the output and provide protection against a shorted load. The selection of SEPIC capacitors, Cs, depends mostly on the RMS current, which can be calculated with Equation 27. The capacitors must be rated for a large RMS current relative to the output power; TI recommends at least 25% higher rating for IRMS. When using uncoupled inductors, use one 10µF ceramic capacitor in parallel with one 33µF electrolytic capacitor and series 2Ω resistor. If coupled inductors are used, then use only one 10µF ceramic capacitor.
