The 3021 BuckPuck LED power module are a line of true current regulated drivers for powering LEDs. The BuckPuck line of LED drivers are the ideal choice for powering all types of high-brightness and highpower LED packages and led arrays.

The line of BuckPuck LED drivers exhibit high efficiency and require no external current limiting resistors or additional heat sinking for operation. A fast response current-sensing circuit makes the 3021 ideal for applications where flashing or strobe operation of the LED(s) is required.
