< html >< body >< p >A6217KEJTR-J is a LED driver, which belongs to PMIC family. This LED driver can be used in many lighting application fields, such as LED signage, LED display, LED lighting fixtures and LED backlight units. It can deliver up to 20W of LED power.

< h3 >Features < p >The A6217KEJTR-J LED driver includes a wide range of features such as temperature tracking and compensation, automatic brightness control, voltage transients protection, built-in frequency jittering and several fault management protections.

< h3 >Applications < p >The primary application of the A6217KEJTR-J LED driver is to provide power and control to a range of LEDs. It can be used in a wide range of commercial and industrial lighting applications, including commercial signage and lighting, automotive lighting, medical lighting, street and area lighting and entertainment lighting.

< h3 >Working Principle < p >The A6217KEJTR-J LED driver works on the principle of a PWM or pulse-width modulation. This technique is used to control the amount of power supplied to the LEDs. The pulse-width modulation technique works by varying the width of the pulse to vary the power supply to the LEDs. This allows the LEDs to be dimmed or brightened as required.

< p >The A6217KEJTR-J LED driver uses a constant current source instead of a constant voltage source as found in traditional LED drivers. This enables more uniform illumination and more efficient operation.

< p >The A6217KEJTR-J LED driver also includes a temperature monitoring feature, which is used to adjust the current supplied to the LEDs. By adjusting the current to the LEDs when the temperature changes, the LEDs are kept running safely and efficiently.

< p >The A6217KEJTR-J LED driver also includes several protective features that can protect the LED lights from damage in case of fault conditions. These protection features include over-temperature protection, overload protection, short circuit protection and over-voltage protection.

< p >In short, the A6217KEJTR-J LED driver offers an efficient solution for controlling and powering a range of LED lights in different lighting applications.
