I need help with a driver.
I am trying to make an adjustable driver from 250 - 750mA for mi 445 diode I bought at SELEM.I have made this diagram with some help from Eudaimonium.
I was told to use these for power.http://www.dealextreme.com/details.dx/sku.19771
But it seems to be too simple, is the the best way to make a driver.
