Hi, i need a driver schematic for 1 watt ir led. Parameters are:
DC forward voltage: 1.4-1.7v
DC forward current: 350mA
Maximun pulse voltage: 1.7v
Maximum pulse current : 500mA
I don't know drop voltage (here http://tinyurl.com/cemzqfu)
I know that the best choice would be a mosfet, but under my hands only some 2n2222, 2n3904, 2n2219, tip127 .
Any suggestion, please?
