Hi all. I've come up with a couple constant-current LED drivers that can handle up to 1A and drive multiple LEDs with PWM. I've made a couple prototypes (work well with Arduino ProMicros) and would like to see if anyone is interested in using them for a project or two. If interested, please see http://braxtron.com
Here are the main features:
*Input voltage range 3V-22V
*200mA to 1A constant current output (user-selectable)
*EN/DIM input for Enabling and PWM dimming
*Ultralow shutdown current (40nA @ 5V input)
Please feel free to either post here or contact me via email (info braxtron.com) if you have any questions.
