AC LED Reference Design - ON Semiconductor

ON Semiconductor has application notes on how to harness the LED lighting technology, this enables you to design your LED based products like Flashlight and LED Ballasts for Home/Office Lighting.

The long term savings on energy cost not only offsets the Initial Investment on LED Lighting but also cuts your expense on a long term for energy and replacement costs. LED Lighting solutions are very reliable, but is is important to integrate it with high quality engineered power electronics. So a Customer/Consumer has to choose quality tested and standardized products and be very shrewd in purchase decisions. Then we have a Bright future for LED Lighting

Low Voltage AC LED Reference Design Board

Powering high brightness LEDs from the AC line utilizing a step down isolation transformer. Drive three 350 mA high brightness LEDs. A linear regulator with two discrete transistors and a sense resistor maintains constant current through the LED Lamps. See also LV AC LED Drive - EEM.

LED Lighting Applications

High Brightness LEDs (HB-LED) and High Power White LEDs for energy efficient Solid State Lighting (SSL).

LED Drive using TPS61042

This Chip from TI is simple to integrate into your designs and this solution is good for production of lighting gadgets, here a consistent quality and predictable performance is easily obtained.

TPS61042 30-V, 500-mA Switch Boost Converter in QFN-8 for White LED Applications

LED-driver application that drives four LEDs with 20 mA of forward current and operates from an input voltage range of 1.8 to 6.0 V.

The entire circuit consists of the control IC, two small ceramic caps, an inductor, a diode, and a current sense resistor. The primary power-supply functions and the secondary features such as load disconnect, overvoltage protection, and PWM dimming have been implemented with a control IC and five small surface-mount passive components.
