Triacs are at the heart of dimming controls for LED lighting. Triacs used in dimmers have normally been characterised and specified for incandescent lamp loads, which have high current ratings for ...

The AP1695 LED lamp driver from Diodes Incorporated optimizes the design of sub-12 W triac dimmer-compatible LED lamps with a dimming range of 1 to 100% and up to 30% reduction in bill of materials ...

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 ...

The EC103 is an isolated smart digital triac control that is low cost and has an excellent digital control performance. It is typically used for isolated control of universal motors such as fluid ...

Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...
