We are all familiar with the snap-on phenomenon of inexpensive TRIAC dimmers that are often used to control incandescent lamps –turn the pot until the light comes (snaps) on and then reduce the ...

Renesas was demoing a new approach to working with triacs at the LightSpeed booth at last week’s LightFair in Las Vegas: The circuit uses a Renesas microcontroller to learn each individual triac’s ...

LED bulbs don’t appear as a resistive load to the TRIAC wall dimmer, though, so dimming an LED bulb using a conventional TRIAC wall dimmer doesn’t yield optimal dimming performance.

The FL7730 circuit is an active PFC controller for single-stage flyback topology application. The device supports both triac and analog dimming.

New LYTSwitch-3 LED driver ICs from Power Integrations support the widest range of TRIAC dimmers. Highly-efficient, solid-state lighting drivers suit both non-isolated and isolated ballast topologies.

Here are helpful safety tips when wiring a light dimmer at home to control how much electricity your bulbs consume. Read the product's instructional manual properly before starting the project.
