What is an LED Driver?

An LED driver is an electrical device which regulates the power to an LED or a string (or strings) of LEDs. An LED driver responds to the changing needs of the LED, or LED circuit, by providing a constant quantity of power to the LED as its electrical properties change with temperature. An LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED or LEDs. LED drivers may offer dimming by means of pulse width modulation circuits and may have more than one channel for separate control of different LEDs or LED arrays. The power level of the LED is maintained constant by the LED driver as the electrical properties change throughout the temperature increases and decreases seen by the LED or LEDs. Without the proper driver, the LED may become too hot and unstable, therefore causing poor performance or failure.

Types of LED Drivers

There are several different kinds of LED drivers. At Future Electronics we stock many of the most common types categorized by output current per channel, supply voltage, output voltage, maximum switching frequency and packaging type. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for supply voltage are 2.3 to 5.5 V, 2.7 to 5.5 V and 3 to 5.5 V. We also carry LED drivers with supply voltage up to 630 V. The output current per channel can be between 250 µA and 50 A, with the most common chips having an output current per channel of 20 mA, 25 mA and 100 mA.

Choosing the Right LED Driver:

When you are looking for the right LED drivers, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Supply Voltage (-0.3 to +20 V, 2.7 to 5.5 V, 3 to 5.5 V,… ), Output Voltage (up to 198 V) and Maximum Switching Frequency (from 200 Hz to 200 GHz) to name a few. You will be able to find the right LED driver chip that can be used as a constant current LED driver, high power LED driver, RGB LED driver, 24v LED driver, dimmable LED driver, in an LED driver board or LED driver IC (integrated circuit) and for any circuits that may require LED driver chips.

LED Drivers in Production Ready Packaging or R&D Quantities

If the quantity of LED drivers required is less than a full reel, we offer to customers many of our LED driver products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers its clients a unique bonded inventory program designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times. Talk with your nearest Future Electronics branch so you can find out more on how you can avoid possible shortages.
