Other Parts Discussed in Thread: LM3410
In the datasheet there is an app note on working with voltages above Vin. I only see notes on 9-14v, but it is not clear what the limits of this is and if sustained voltages up to 18v would cause issues. I like the simplicity of this LED driver but need to pull from 12v battery source in order to avoid unnecessary power conversation. Other devices are more complex than what I need so I like the idea of using the simple LM3410 as a display backlight driver. The application not below also is close to my application needs, just with 6 LEDs and running a forward voltage of about 16v.
