The Basics Behind Constant-Current LED Drive Circuitry
Nettet26. feb. 2024 · A constant-current LED driver is based on a buck converter circuit, which is essentially a variant of a step-down switch-mode power supply. It’s pretty simple at a “black box” level, as shown in the diagram at right. It accepts a fixed-voltage power supply (V ps) and a control input, and drives one or more LEDs wired in series.The selection … NettetA current-regulated LED driver is an AC-DC or DC-DC converter with output tailored to the electrical characteristics of the array of LEDs. It provides accurate output current … bruh faint
