Can anyone out there point me to an efficient solution for driving a couple of 1A IRLEDs from a 7-12V source, with I2C control? I can do it with a small micro to provide PWM into a conventional boost reg set as a constant current source, but that seems like a lot of messing about for something that should be a one-chip solution. Unfortunately, I'm just not finding it. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
