This design example report presents a 9.5 W TRIAC dimmable, high efficiency, power factor corrected, isolated LED driver employing LYTSwitch-3 LYT3315D. Its operating input voltage ranges from 90 VAC ...
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 ...
Triacs are used to control ac mains loads in home appliances, and commercial and industrial equipment. In the majority of applications, the triac will dissipate sufficient power to make thermal ...
