EL1848IWT-T7A

LED drivers are used in a variety of applications, from large commercial and industrial lighting projects to residential houses and small businesses. The need for LED drivers arises from the fact that the electrical energy needed to power LED lighting is often different from the voltage supplied from the distribution grid. To ensure that LED lighting is properly powered, LED drivers step up or down the voltage to a level that is compatible with the LED light source. They also act as a constant current source so that the LED is not damaged by high voltage, and help protect the LED light source from a variety of electrical problems.

The EL1848IWT-T7A LED driver is purpose-built to power LEDs in a variety of applications. It is an integrated LED driver based on a buck switching topology with a wide range of current outputs. The device features built-in line regulation, adjustable cycling frequency, soft start, feedback current limit, and over-voltage protection. Additionally, it provides 18V input shutdown and open-drain output status.

The EL1848IWT-T7A’s low-noise, high-efficiency DC/DC buck converter is ideal for driving LEDs in automotive and industrial lighting applications. It also offers a wide range of current outputs with a maximum output current of up to 20A, allowing for the powering of larger and brighter LED lighting applications. The integrated protection features of the device make it both reliable and safe, ensuring that it can withstand a wide range of electrical conditions.

The EL1848IWT-T7A operates according to the principles of the buck switching topology. It utilizes a power switch, in this case consisting of MOSFET transistors, along with an internal feedback loop to accurately control the output current. As the input voltage increases, the power switch turns on and off at a fixed rate, regulating the output current and maintaining a steady constant current output. The feedback loop also controls the switching frequency so that it is stable and consistent, helping to minimize noise and maximize efficiency.

The EL1848IWT-T7A is well-suited to applications such as automotive lighting, LCD backlighting, illumination lighting, and even military and aerospace applications. Its wide range of current outputs and integrated protection features make it extremely versatile, and its buck-switching design ensures efficient and accurate current regulation. It is a great choice for applications that require reliable, high-efficiency LED driver solutions.
