1) The input EMI filter has to be evaluated in according with the final application. The values are only given as hint.
2) The saturation current has to be define in according with the maximum current required by the application.
3) For optimum dynamic behavior, C4 and C5 = 22 µF ±20%, 16 V ceramic low ESR.
