Our main products include TEC controller, laser driver, tec module, resistor kits and so on. Today I will introduce an evaluation board ATLS214EV1.0 The ATLSxA214D is a series of high efficiency constant current laser drivers for driving multiple laser diodes. ATLS214EV1.0 is designed for evaluating these series laser drivers conveniently.
 
Since the ATLSXA214D series laser drivers come with up to 6A current, the evaluation board provides good heat dissipation as well as power supply and connection ports, totally four ports. There are terminal blocks and solder pads for input and signal ports. They are used for connecting different wires. The green one provides a special test point for ammeter. It’s easy to read dynamic data during experiment.
 
The switch S1 can turn the driver on and off. When S1 is in the middle Standby position, the driver will stop working, but the internal 2.5V voltage reference is still working. There is a PCN switch S2 in the evaluation board. The laser driver has two current setting ports, LISH and LISL. LISH or LISL is selected by PCN switch S2. LISH and LISL current set provides internal controller and external controller, which are controlled by the switch S3 and S4 respectively. Internal control is realized by adjusting the two POTs, W1 and W2. External control is realized by external signal to set the current. When turn the black switch S5 onto the upper position, the 2 multi-meter leads are connected to AMMTR+ and AMMTR-, the output current can be measured by the current meter.
