Let's look at a series of laser drivers ATLSxA104 with ultra-low output noise, small size, and current limit protection. There are 5 models of this series of laser drivers, among which the one with highest output current can drive 1.5A diode lasers. The “xA” in the part number represents the maximum output current of the laser driver module, which can be: 100MA, 250MA, 500MA, 1A and 1.5A respectively. The laser driver is powered by a 5V supply, and the output voltage is 0.5V to 3.6V. The controller has a temperature compensation network, so even if the controller temperature increases, the output current will remain unchanged. There are 2 packaging versions available: DIP through hole package and SMT surface mount type.
