Hi everyone,

i'm looking for a laser diode driver circuit schematic that will give me a current output upto 658mA. Any input is greatly appreciated.

Sam Goldwasser claims up to 800mA without heatsink, up to 1200mA with heatsink.

 

Thanks thingmaker, i simulated this with pspice and somehow it would not give me anything near 800mA. if you dont mind please help me take a look at my pspice file. http://download.yousendit.com/E13CF25E233F4A59

Thanks for all your help!
