LED (Light Emitting Diode) is a type of semiconductor that emits light when current passes through it. LED lights have great advantages over traditional incandescent and fluorescent lighting, such as higher energy efficiency, longer life, improved durability, and better light quality. With the rapid development of LED technology, LED lighting has been widely used for commercial and residential applications, such as office, home, and outdoor lighting.

This article is about the A8480EEJTR-T, a PMIC (Power Management Integrated Circuit) – LED Driver, which is typically used to drive LEDs in the various application fields. This driver is designed to deliver high power and current levels, with a 0.6V to 20V input voltage range and a 4A to 40A output current range. It also features adjustable current regulation and temperature protection.

The A8480EEJTR-T is a very flexible driver that can be used in a variety of lighting applications. For example, it can be used to power LEDs in automotive, industrial, commercial, and residential lighting applications. It can also be used in automotive daytime running lights, LED display screens and signs, and LED stage lighting.

The working principle of A8480EEJTR-T is based on a buck converter topology. It includes a voltage-controlled switch and a transformer to convert the AC input voltage to the required DC output voltage. The transformer is usually composed of a primary and secondary winding, and the voltage is controlled by a feedback circuit with the integration of a voltage divider.

The A8480EEJTR-T can also be used as a universal lighting device, as it offers multiple dimming options such as Analog Voltage, PWM, and Digital control. In addition, it can also provide protection against overvoltage, under voltage, overload, and over temperature.

LED lighting is becoming increasingly popular, and PMIC – LED Drivers like the A8480EEJTR-T are a key component in achieving the energy-efficient and long-lasting lighting solutions that consumers demand. This driver is a reliable, cost-effective solution for a wide range of lighting applications.
