ATLS6A214 is a high voltage constant current laser driver. It can drive multiple laser diodes with high efficiency and low noise. It has both a wide input voltage range from 5V to 14V and a wide output voltage range from 0.8V to 0.75VVPS. It has high current output capability. The output current can go up to 6A without using a heat sink. Its volume is very small, and two kinds of packaging are available: DIP and SMT.

Here is an internal block diagram of ATLS6A214:

The internal block diagram shows that the laser driver provides these the functions: standby control, shutdown control, laser current setting, laser current monitoring, over temperature protection, loop good indication, soft start.

This laser driver ATLS6A214 can be used with the evaluation board ATLS214EV1.0 and load assembly ALLD10A14V. Since high power laser is usually quite expensive, we have developed a load assembly and evaluation board to avoid making costly errors in the process of product evaluation. The load assembly can be used to simulate how the actual laser diode would be driven by the laser driver.
