Infineon Technologies AG has introduced the new LED driver IC ILD8150/E. It features an innovative hybrid dimming mode technology for achieving 0.5% of the target current. With a supply voltage range ...

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2, and ...

I made this dimmer circuit because I have a cheap chinese LED lamp that doesn’t have the option to dim its light. It is a simple PWM dimmer built with the well-knows 555 integrated circuit and a power ...

The advent of LED lighting in the past few years has now matured to the point where sweeping changes exist in the way we think about illumination. LED lighting was once the darling of scientists and ...
