LED drivers are used to control LED lighting systems. They provide a constant current source to ensure that the LED light does not flicker or turn off. The BD8379FV-ME2 is a LED driver in the PMIC series that is used to control LED lighting systems. This article will explain the application field and working principle of BD8379FV-ME2.

Application Field

The BD8379FV-ME2 is used in a wide variety of LED lighting applications and is commonly found in LED strips, LED modules, LED spotlights and LED bulbs. It is suitable for use in high-performance LED lighting systems, as it provides a constant current source to ensure that the LED light does not flicker or turn off. It is also capable of driving up to two LED channels in parallel, which means that it is capable of providing a higher current for more demanding applications. It also comes with a variety of protection functions, such as over-current protection, thermal protection and short-circuit protection.

Working Principle

The BD8379FV-ME2 works based on a regulated boost converter topology. It has an internal error amplifier which compares the output current and the reference current, which allows it to control the output current of the LED lights. The internal error amplifier also maintains a constant current output even when the input voltage varies. The BD8379FV-ME2 also features an adjustable switching frequency, so that it can be fine-tuned to the specific application, reducing switching losses and improving overall efficiency.

The BD8379FV-ME2 also comes with over-voltage and over-temperature protection functions. The over-voltage protection function will shut the device down in the case of a voltage surge, ensuring the safety of the system and of the LED lights. The over-temperature protection function will shut the device down in the case of an abnormally high temperature, ensuring the safety of the system and of the LED lights.

Conclusion

The BD8379FV-ME2 LED driver is an excellent choice for high-performance LED lighting applications. It is capable of providing a regulated constant current source to ensure that the LED lights do not flicker or turn off. It also comes with a variety of protection functions, including over-voltage, over-current and over-temperature protection for improved safety. The adjustable switching frequency of the BD8379FV-ME2 ensures that it can be fine-tuned to the specific application, improving overall efficiency.
