LED light source driving circuit

- Dec 10, 2019-

The driving circuit of the LED light source converts the 12V DC voltage into a stable constant current source. The design of the circuit is based on the principle of simple and cost-saving, and should be selected from a large number of LED driver chips that can complete the design requirements of this circuit. A chip that is better, has a simple application circuit, and has a relatively low price/performance ratio. Therefore, selecting a driver chip with few peripheral components of the driver circuit is the primary consideration for production cost.
