Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

Typical requirements for industrial LEDs. Designing an LED gate driver using an industrial digital input chip. Ruggedness characteristics of the new gate driver. Industrial control systems universally ...

The circuit in Figure 1 combines a VBE-referenced current source with a current mirror to implement a simple two-terminal, fully floating LED current sink or source. This approach is well-suited for ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

LED-based signage and matrix displays are bringing new dimensions of versatility and eye-pleasing visual effects to a growing number of outdoor and indoor applications. Recent advances in LED ...
