Parameters Recommended: Component Code Above are typical parameters, please adjust according to actual environment. Positive negative dual output product Single output product For normal request on ripple& noise, external recommended to use C2, C5 only; If have strict request on it, above circuit is recommended. Note: 1. C2,C3,C5,C6 use high frequency low resistance electrolytic capacitors, and total capacitance cannot exceed the maximum capacitive load on this manual, or the module cannot start up normally. 2. Under capacitive load, please assure at least 3% minimum load, or the output of module...
