Driver IC: LED is a light-emitting diode, when the number of diodes or the tube is relatively large power consumption, it needs to be driven, and it is a few levels of drive, the several levels of drive to an integrated electronic chip, this chip is called the driver IC, simply put, to play the role of providing compensation current to the diode.
The working principle of led driver ic:
The chip contains a constant current generating circuit, which can set the output constant current value through the external resistor. The switch time of the output channel can be controlled through the enable side of the chip, and the switching frequency is up to one megahertz (1MHz). The current output response is extremely fast, supporting applications with high color level changes and high picture refresh rate. Built-in open circuit detection,
Overheat power off, and overcurrent protection function, greatly improve the reliability of the application system.
It is an integrated circuit chip that is used to control and drive other electronic components or devices. Driver ics are usually used to control motors, LED lights, displays, audio equipment, etc., which can provide the necessary current and voltage to make the controlled equipment work properly.
