Note:

1.

It’s essential to connect VCC pin with a SMD ceramic capacitor (0.1

F~0.47F) to

filter out the undesired switching noise for stable operation. This capacitor should be

placed close to IC pin as possible

2.

Connecting a capacitor to COMP pin is also essential to filter out the undesired

switching noise for stable operation.

3.

The small signal components should be placed close to IC pin as possible.
