Hello everyone,
As I said in my title, I'm trying to drive a 10.2v, 140mA LCD backlight (LED array) from a 3.7v, 2000mAh battery. I have looked into several methods of doing this, and the one that stands out to me seems to be some kind of boost converter. I have never built a boost converter before, and was wondering if this is the best possible method.
I currently have the LCD operating just fine, and am running the backlight from a 16v power supply through a 50ohm 5W resistor. The resistor is dissipating a lot of heat though, and I am not sure what the limitations of a boost converter are.
Thanks,
Justin W
