This design example report describes a 20 W high efficiency TRIAC dimmable, power factor corrected LED driver employing LYTSwitch™-4 LYT4314E. This design operates an input voltage ranging from 190 ...
CARROLLTON, Texas –– February 29, 2008 –– Everlight Electronics Co. Ltd . (TSE: 2393) introduces a complete portfolio of 6-pin DIP random-phase and zero-cross triac driver optocouplers offering the ...
The new PDA015N constant current waterproof LED drivers are compatible with virtually all leading edge, trailing edge, & smart dimmers, eliminating flicker, shimmer, & reduced dimming ranges in both ...
To understand the technology associated with practical LED dimming we first have to look at the technology associated with triac-based incandescent lamp dimmers. The typical triac lamp dimmer circuit ...
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 ...
