Light emitting diode (LED) drivers are components used to control and manage the power supply of individual LEDs. As a result, they play an important role in managing the performance, longevity, and overall supply of LEDs, ensuring they are used in optimal condition as part of the related lighting systems.

LED drivers are categorized according to the type of output control they provide, such as pulse-width modulation (PWM) and constant current. Aside from these two types, LED drivers may also provide features such as dimming, over-voltage, over-temperature, and short-circuit protection. Thus, LED drivers are equipped with a wide range of protection such as current limit, transient and thermal protection, and fault protection.

3895 Application Fields and Working Principle

3895 is an LED driver designed as an AC/DC LED driver primarily used in LED lighting applications. It is designed to be immune to harmonics that may be encountered in the power mains, yet still offer a high level of system performance. The 3895 LED driver combines low-noise AC/DC control and a precision current regulation circuit for efficient, low-cost, highly reliable LED solutions.
