This app note provides a simple circuit to drive high brightness LEDs. It requires minimum external components and it provides both linear and PWM dimming. Ideal for Osram, Lumileds, Cree, and Nichia ...
This dimming controlled LED driver circuit is designed using LM3409 P-channel MosFET controller for step-down (buck) current regulators.The LM3409 devices use Constant Off-Time (COFT) control to ...
In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...
This file type includes high resolution graphics and schematics when applicable. Light-emitting diodes (LEDs) are semiconductor devices that emit light when an electrical current passes through ...
Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...
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 ...
