1. C1, C2 is required for best performance and should be fitted close to the converter
pins.
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. No parallel connection or plug and play.

The R1, R2 in the above table are used to set the output voltage. If no need to adjust the output voltage, connect a ceramic capacitor to
GND with 470pF typical value for increase immunity. Insure the output voltage is in the adjust range or else may cause permanent damage to the
device. Fine-tune output voltage must appease Vin-Vo>2V.
