Note:

1. 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.
