Recently, white LEDs have made sizable performance gains by squeezing extreme luminous density into ultra-compact packages. The latest white LEDs hold numerous advantages over more conventional lighting, including improved spectral characteristics, sh...

Automotive, industrial, and FireWire peripherals all call for high-efficiency, space-saving power supplies with high current capabilities at very high voltages. The problem is that high-voltage, monolithic (where the power switch is included)...

Disk drives, ADSL modems, notebook computers, and other data-acquisition circuits require high-current, ±5-V power supplies with switching frequencies above 1.1 MHz to avoid interfering with noise-sensitive circuitry. A very simple, compact, and...

High-brightness LEDs are an inexpensive, robust, and green replacement for halogen light bulbs. This Idea for Design shows you how to apply an AC LED driver to convert the usual 12 or 24 V AC halogen-bulb supply to an appropriate DC voltage for LEDs...

chips capable of implementing boost or sepIc converters are tailored to the headlamp application, integrating features that enable high brightness LeDs to be more readily applied in place of traditional fi lament style and HID bulbs...

High-power LEDs promise a growing number of advantages, including lower long-term cost and longer life, over both incandescent light bulbs for interior...
