Cxac8563 is the original side feedback mode, and optocoupler and TL431 can be omitted. The no-load loss (230VAC) of the chip is less than 30MW. In constant voltage mode, quasi resonant and multi-mode technology are used to improve efficiency and eliminate audio noise, so that the system can meet the 6-level energy efficiency standard. The adjustable output line compensation function enables the system to obtain a better
Good load regulation. In constant current mode, the output current and output power can be adjusted by RS resistance of CS pin. The chip provides a comprehensive protection function, including cycle by cycle over-current protection, over-voltage protection, open-loop protection, over temperature protection, output short-circuit protection and CS open / short-circuit protection
