DC/DC Converter URB1D_YMD-6W Series Design Reference 1. Typical application All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery. If a further decrease of the input and output ripple is required, properly increase the input & output of additional capacitors Cin and Cout or select capacitors of low equivalent impedance，and ensure the capacitance should be lower than the max. capacitive load of the product. Fig. 3 FC-C01D is the EMC auxiliary component of our company. Input voltage range: 40V-160V; FUSE: Choose according to customer...
