Step-Down (Buck) LED Drivers
Step-Down (Buck) LED drivers are ideal for applications where the input voltage is above the LED voltage, as in many automotive or industrial applications. These LED drivers offer the highest efficiency, lowest noise, and the smallest footprints. Other features include integrated Schottky diodes, accurate LED current matching and multiple output capability.
