ATLS500MA202D laser driver is an electric module with up to 500MA constant current. It can be used to drive laser diodes with low noise and high efficiency. As shown in Figure, this laser driver has a compact size and provides DIP package for users. By using the laser driver, many functions can be realized, such as, laser constant current control, laser current monitoring, over current and thermal protection, switching frequency synchronization and so on.

ATLS500MA202D laser driver comes with the frequency synchronization function, which allows using an external digital signal to synchronize the internal PWM output stage. When using multiple laser drivers on the same PCB, it can eliminate frequency beating interferences from other electronics.
This laser driver needs the external signalfrequency between 520 KHz and 800 KHz. If you want to use other frequency, please contact us, we can adjust the internal PWM frequency for you.
