Design of switching power supply based on VIPER22A
Summary:
The design of switching power supply based on VIPER22A uses VIPER22A chip to design a kind of switching power supply. Different design methods are adopted in the pre-stage voltage input and post-stage voltage sampling, and the principle and specific implementation method of each level circuit are given. The test proves that the switching power supply has the characteristics of simple circuit, high reliability and strong practicability.
The VIPER22A switching power supply circuit is applied as follows:
The internal structure of the VIPER22A chip is as follows:
The above is its application circuit, detailed circuit diagram analysis can be found in the PDF document!
