A analog circuit is adopted to design a voltage control current source,whose output is up to 10 A. A function for DC operating point setting is added according to operating characteristics of semiconductor laser. It has the functions of power on protection,slow start?up,output enabled delay,output current limitation. The derivation process of current source output is given in this paper. The single 5 V power supply is selected in this design,which has the characteristics of little size and high reliability.
