I need a circuit designed (please include part numbers). The circuit will allow LEDs to be powered by 120 AC 60 Hz and must allow the LEDs to be dimmed by a device that I have that uses Pulse-width modulation. I will use the circuit to build 3 seperate devices, 1 using Green LEDs, 1 using Red and 1 Blue. The output of the LEDs should be close to the output of a 10-20 watt incandesent light bulb and should have a beam width should atleast 60 degrees and should allow atleast 6 LEDs bulps. The circuit also should allow any number of the LEDs to fail without having any negative affect on the others.

We can provide the circuit design with in depth information as we have huge IC design experience for power management applications.
Maybe I can do the project sooner, but 8 days is the max! And you can be sure that it will work very well.
I have designed many power circuits for many years. I will make sure that the parts I use are easy to buy, not expensive and easy to assemble. The circuit will work well and it will continue to be reliable. I have also Plus
