The diode laser driver is divided into two types: AC input and DC input. The former accept AC main as the power source, the voltage can be 110V in some countries, 220V or 240V in some other countries. The latter accept different ranges by the DC voltage, such as 3.2V to 5.5V, 4.7V to 16V, 4.7V to 28V, etc. There are also different series in the DC input laser driver: TLSxA212, ATLSxA214, ATLSxA216, ATLS4A217, ATLSxA218, etc. Now let's take a look at the high voltage constant current laser drivers ATLS15A218.
The development of ATLSx15A218 is very important and quite valuable, because it is very difficult to meet the following characteristics; It has both, a wide input voltage ranging from 5.5V to 28V and a wide output voltage ranging from 0.1VVPS to 0.8VVPS. There is no need for heat sink with this high efficiency. The efficiency can go up to 90%. It has high current output capability up to 15A. This laser driver is packaged in DIP package.
We have specifically designed the evaluation board to assess the laser driver more efficiently. The load assembly ALLD10A14V, is designed to emulate laser diodes for evaluating the ATLS15A218 series of laser drivers. We have made it very convenient for the laser driver ATLS15A218 to collocate with the load assembly ALLD10A14V and the evaluation board ATLS218EV1.0.
We have many other laser drivers. If you want to know more about laser drivers, please visit our website:
