The cxac8586 chip integrates PWM controller and power MOSFET, which is suitable for low power off-line switching power supply. The chip provides complete intelligent protection functions, including over-current protection, over-voltage protection, under voltage protection, over temperature protection and soft start. The intermittent operation mode can reduce the power consumption of the system when it is in standby mode, and the buffeting technology can improve the EMI characteristics. The chip also has a built-in high-voltage start module to ensure that the system can start quickly
