The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...

In some LED lighting applications, precise light intensity control is a must. For instance in shops where multiple LED lighted panels are installed one next to the other, the light intensity and light ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

NXP's PCA9685 is an I²C-bus controlled 16-channel LED controller optimized for LCD Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 ...

High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.
