/ Converter Design Reference 1. Output load requirements To ensure that the module can work efficiently and reliably, its output min. load shall be no lower than % of the rated load when using, or the output ripple may increase rapidly. Ensure that the product working load must be higher than % of the rated load. 2. Typical application All the / converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery. If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and or select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.
