Cxac8562 integrates ultra-low standby power quasi resonant primary side controller and built-in 650V high avalanche power MOSFET, which is used for charger, adapter and built-in power supply

Cxac8562 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 makes the system obtain better load adjustment rate. 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
