This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with A Digital Constant Current Power LED Driver The ...

A suitable circuit is a switchmode- regulator LED driver designed for ac lighting that requires a high power factor (PF). The ideal load, with 100% power factor, is a pure resistor.

Your 10W LED will need about 10.5V and your constant current circuit will have to drop the difference from the supply voltage. If you feed 14V into the circuit then the 3.5V difference will become ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter&… ...
