摘要：
A constant current laser driver circuit that will drive a laser diode in a constant current mode from a 6 to 12 volt battery supply. The laser driver consists of two main sections. The first section converts the 12 volt input to a 2 volt output using ultra-low resistance power mosfets and an inductor. The current sensing amplifier senses the current flowing through the laser and sends a feedback signal to the switching section, which causes it to adjust the output voltage to keep the laser driving current constant.
