(1) Capacitance values do not include any derating factors. For example, if 5.0 µF is required and the external capacitor value reduces by 50% at the required operating voltage, then the required external capacitor value would be 10 µF.
(2) This includes all capacitance to the Type-C receptacle.
(3) Maximum capacitance allowed on TVSP pin to ensure proper decode of device configuration during boot.
(4) See applications section for recommended L and COUT combinations.
