The ATLSxA202D series of laser drivers have slightly different pin out as that of the ATLSxA201D series of laser drivers. This series of laser drivers has a synchronization function pin which allows using an external digital signal to synchronize the internal switching frequency of the PWM output stage. This function is useful when using the laser drivers with a switching power supply that has similar switching frequency or while using multiple such laser drivers on the same PCB, to eliminate the beating frequency interference. They are designed for driving laser diodes with low noise constant current with very high efficiency.
The "xA" in the part number specifies the maximum output current of the laser controller and you may choose from the following output currents: 500mA, 1A, 2A, 3A, 4A or 6A. The module is packaged in a metal enclosure, emitting zero EMIs, and has our DIP mounting package. These laser drivers are of 100 % lead (Pb)-free and RoHS compliant.
