FAQ about PMIC - LED Drivers
-
1. What is the difference between an LED driver and a ballast?
LED drivers: Designed specifically for LEDs, they are usually used to adjust the output current to meet the requirements of LEDs.
Ballasts: Traditionally used for fluorescent lamps or other gas discharge lamps, they control the high voltage at startup and limit the operating current. Although some modern electronic ballasts can also provide constant current, their original design and application areas are different from LED drivers. -
2. Can I run an LED without a driver?
Yes, but additional circuits (such as resistors) are required to limit the current. However, this method is less efficient and difficult to maintain a stable current, which may lead to poor LED performance or shortened life.
-
3. Why do I need to program an LED driver?
Programming is usually for advanced drivers with programmable functions, such as achieving finer dimming control, color adjustment or other intelligent functions. This allows users to customize the behavior of the driver according to specific needs.
