Notice
-
• Take care not to cause interference due to wiring of IN and OUT1.

-
• Wiring need to be short to prevent carrying of the noise. If the noise is carried, insert a capacitor between IN and IN .
• In application of connecting the CT pin to GND, lock protection and restart function are not effective.
