The Envistia 20mA LED Driver Module is a simple LED power supply module (constant current regulator, or CCR) using a single 20mA constant current source/LED Driver IC that solves the problem of powering your LEDs and eliminating the current-limiting resistors required with other driver circuits.

When a voltage up to 45V DC is applied, it actively adjusts its own resistance to allow 20mA (+/- 2mA) to pass through. This makes it a perfect replacement for current-limiting resistors in LED circuits, and eliminates the need to calculate current-limiting resistor values or worry about a varying voltage source.

With its high maximum input voltage, it can drive multiple LEDs in series. It is perfect for 12V automotive applications because it ensures that your LED is continuously powered with a regulated 20mA regardless of battery voltage spikes, sags and fluctuations.

The module operates with a DC input voltage of 2V to 45V. It requires ~2V overhead voltage to operate, therefore the minimum voltage is 2V + your LED voltage. For example, if you are driving a single LED with a forward voltage of 3V, the minimum voltage required is 5V (3V + 2V).

The modules are provided on a scored circuit board that can easily be broken apart. Two 0.1" header pins are included with each driver.
