There are some lighting applications which uses stepdown transformers to bring the mains voltage down to 12V AC. Power supply IC company Dialog Semiconductor has designed LED driver iW3662,which can ...

MR16 halogen lamps normally operate from a low-voltage AC source typically generated by a low-frequency AC transformer or by a high-frequency electronic transformer. In most MR16 applications, the ...

A white LED delivers a wide color spectrum and better visibility than do monochromatic LEDs. However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus ...

In Part 1 of this three-part series, we took a brief look at the need for a consistent and frequency-independent ground plane for LED drivers. In Part 2, we take a look at how facility power systems ...
