  • Abstract
    We use switching power supply technology that is controlled by digital to implement a constant current output circuit. The circuit consists of the implementation of a new slow-start and high stability of output current control method, and is capable to drive a low-power laser diode. Output current can be adjusted from 0 to 3A, with the current stability of 0.50/00.
