DC/DC Converter K78xx-1000(L) Series Fig. 4 Positive and Negative output parallelling application circuit Note: 1. When the products used as negative output and the input-voltage under (Vin-min+2V),C1 and C2 must be added in the circuit, and they should be placed as near as the products' footprints. Others apply to the application-environment . 2. The capacitance of C1,C2 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic capacitors may also suffice. 3. When the products used as the circuit like figure 7,an inductor named as LDM up to...
