Here is a nice hack you may find very useful if you have a cheaper bench power supply that supports constant current limit protection (CC mode) and the only way to set or check your max current limit ...

The LDB200 series of LED power supplies from Excelsys offer 200 Watts of constant current / constant voltage power in an IP67 rated, low profile, aluminum case measuring only 7.80 x 2.48 x 1.38" with ...

The purpose of this project is to control the current across a load by using pulse width modulation for maximum power efficiency while being constructed on a breadboard. The project accommodates the ...

This post sponsored by Texas Instruments. The UCC2871x family of flyback power supply controllers provides isolated-output constant-voltage (CV) and constant-current (CC) output regulation without the ...

Normally, when a project calls for addressable LEDs, we just throw a strip of WS2812s and an Arduino together, cobble together some code from the examples in the FastLED library, and call it a day. We ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
