C1 & C2 (C3 & C4) are required and should be connected as close to the module pins as possible. 2. Refer to Table 1 for C1 and C2 (C3 and C4) capacitor values. For certain applications, increased values for C2 and C4 and/or tantalum or low ESR electrolytic capacitors may also be used instead; 3. When using configurations as shown in figure 3, we recommended to add an inductor (LDM) with a value of up to 10μH which helps reducing mutual interference; 4. Converter cannot be used for hot swap and with output in parallel. EMC RECOMMENDED CIRCUIT Figure 4 Table 2 Recommended external circuit components Note: 1.
