Led Driver Calculator


Calculating LED driver requirements is essential for designing efficient lighting systems. The LED Driver Calculator provides a handy tool to simplify this process. This article guides you through using the calculator, understanding the formula, and provides a working HTML and JS code for implementation.

How to Use

To use the LED Driver Calculator, follow these steps:

  1. Input the values for LED forward voltage, LED forward current, and the number of LEDs.
  2. Click the “Calculate” button to obtain the required LED driver voltage and power values.
  3. The result will be displayed, indicating the appropriate LED driver specifications.


The formula used in the LED Driver Calculator is as follows:



Let’s consider an example where the LED forward voltage is 3.5V, forward current is 20mA, and there are 5 LEDs in the circuit. The LED driver dropout voltage is 2V.


Q: How do I determine the LED forward voltage and current?

A: Refer to the LED datasheet for specifications.

Q: Why is the dropout voltage necessary in the calculation?

A: The dropout voltage ensures proper regulation in the LED driver.

Q: Can I use this calculator for other types of LEDs?

A: Yes, as long as you have the correct forward voltage and current values.


The LED Driver Calculator streamlines the process of determining the necessary specifications for LED drivers, making the design of lighting systems more efficient.
