Currently, switching power supply is developing towards the direction of the integration and intelligence. Nowadays, highly integrated powerful single-chip switching power supply represents the mainstream direction of the development of switch power supply. TinySwitch - III chip integrates many kinds of protection mechanisms, such as input voltage, output overvoltage, and thermal-shutdown protection. It can effectively keep the chips in high reliability in a variety of different environments. This paper mainly introduces the functions of TinySwitch - III chip and external input over-voltage protection circuit based on the chip design.
