- Translation from original language as provided by authorA digital power supply for laser diode will be designed in this paper. As we know, laser diode is formed from P-N junction as well as diode. It is powered by injected electric current, and a tiny variation of current may bring about large changes on the laser's power output. So the driver should be design as constant current and have lower ripple. Linear power supply is used in traditional. With the developing technology of power electronics, switching-mode power supply (SMPS) with high efficiency and high power density gradually replaces the linear constant-current source especially in large power field. The development of laser diode and the work principle are introduced in this paper first. In order to get the requirements of laser diode for power supply, the power-current (P-I) characteristic and voltage-current (V-I) characteristic are analyzed. In the next place, a digital constant current SMPS based on DSP are designed including Power topology str
