One of the biggest challenges for new, energy-efficient CFL and LED-based lights that will replace incandescents is working with existing triac-based dimmer switches. Triac dimmers vary widely in both ...
Fairchild Semiconductor introduced the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC) for triac and analog dimming compatibility. The FL7730 circuit is ...
The LM3445 from National Semiconductor enables a full 100:1 range of offline, uniform, flicker-free dimming for high-brightness LEDs with a conventional TRIAC forward or reverse phase-control wall ...
One of the shortcomings of the DIAC trigger diode circuit is that the timing capacitor (C1) does not automatically discharge to zero volts when it triggers. In fact, the residual voltage is an unknown ...
When operating a standard light switch, your choices are limited to turning the lights on or off. However, a light dimmer provides more versatility. Depending on the type of dimmer you choose, you can ...
