18/5000 LED qūdòng xīnpiàn fēnxī gàosù nǐ tā jiùjìng shì shénme LED driver chip analysis tells you exactly what it is
In fact, the LED driver chip is a PWM control chip. After the constituent circuits work normally, the voltage obtained by detecting the current of the LED on the current detection resistor is fed back to the chip to control the internal PWM duty cycle so as to adapt to changes in the characteristics of the LED itself. The resulting current and voltage fluctuations keep the LED's current constant.
Teng Huatai for IC design companies to understand what kind of IC market, what price should be appropriate. The price will change at any time only for reference. Quality and price are factors that determine whether to use, it is very important to meet the product design quality parameter requirements! The price is more important!
As more and more IC design manufacturers have joined the LED design team and designed many models, we will discuss in detail from the aspects of cost performance, how to choose the right IC, and which ICs are most suitable for the products we are planning to design.
The above is some information that Shenzhen LED driver IC manufacturers have arranged for you, but also want to learn more about IC information, you are welcome to come to consult .....
