Supertex, Inc. has introduced the HV9910, which it describes as the industry's first universal, high brightness (HB) LED driver IC. The HV9910 is a highly flexible and simple LED driver IC that ...

A white LED delivers a wide color spectrum and better visibility than do monochromatic LEDs. However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus ...

Design considerations for the four key LED functions. LEDs are pervasive, and while the growing number of LED applications can be daunting for any power engineer, it doesn’t have to be. LED drivers ...

Tagging wildlife is never straightforward in the best of times, but it becomes a great deal more complicated when you’re trying to track flying insects. Instead of trying to use a sensor package, ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

This project is a simple universal Power LED Driver. The Power LED can be controlled by the built-in PWM signal generator or driven from an external drive signal depending on how the hardware is ...
