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 ...

This light dimmer control has active timing capacitor reset or AC line zero-crossing synchronization. The 13 additional components are garden variety and cost less than $2. Performance at the low end ...

Fairchild Semiconductor introduced the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC) for use with triac and analog dimming compatibility. Fairchild ...

Lamp dimmers and their circuits must be compact, energy efficient and able to operate reliably in confined spaces. Lamp brightness is varied by controlling the conduction time of each half-cycle of ...

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 ...
