C1 and C2 are required and should be fitted close to the converter pins. 2. The capacitance of C1and C2 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic capacitors may also suffice. 3. No parallel connection or plug and play. TYPICAL APPLICATION CIRCUIT APPLICATION EXAMPLE For more information, please visit the product page.
