A PWM controller and a high avalanche power MOSFET are integrated in the chip, which is suitable for low power non isolated switching power supply. The chip provides complete intelligent protection functions, including over-current protection, over-voltage protection, under voltage protection and over temperature protection; Frequency down modulation technology is helpful to improve EMI characteristics. The chip also has a built-in high-voltage start-up module to ensure that the system can start quickly. The peripheral components of the application system are more concise.
