High Voltage Constant Current Laser Driver

To better meet the requirements for driving a series of laser diodes with high voltage and constant current, ATLSXA214 series laser drivers/controllers are developed: ATLS4A214 and ATLS6A214. The wide output voltage range, 0~15V, allows driving one or more multiple serial laser diodes at the same time, for up to 4A, 6A well controlled current at high efficiency.

ATLS214EV

This evaluation board is on the 4 edges of the board, it features solder pads for all the interface ports provided by the laser driver. The solder pads can be used by clips or soldered with wires for connecting to external circuits. The power supply input is connected on the upper edge of the board. The incoming wires can be soldered on the pads, or clipped by alligator clips, or use the terminal block and tight the wires by the screws. In the upper middle of the board, there is an LED. When the controller works properly, it will be lit up. On the left side of the controller, there is a terminal block. It can be used for connecting wires going into the ports of the laser driver. On the lower side of the laser driver, there are 2 POTs (Potentiometers) for setting the lower and upper values of the set-point current.
