Hi all,
I'm trying to PWM a high brightness LEDs in parallel (http://d114hh0cykhyb0.cloudfront.net/pdfs/spmwht5225d5waq0s0.pdf) and I was hoping to use an Arduino and a CAT4101 driver (http://www.onsemi.com/PowerSolutions/product.do?id=CAT4101). I was hoping that someone could tell me if this would work or not, or if there's something I need to add to the circuit.
The LED has about a 3 V forward voltage, and so I'm wondering if I can use the 0-5V PWM pins of the Arduino to drive it using the CAT4101 with a 3V power supply. I've uploaded a sample schematic here.
Thanks for any help
