ATLSXA212 Laser Drivers

In order to meet the need for driving high voltage diode lasers or driving a serial of diode lasers simultaneously, we have developed ATLSXA212 series laser drivers/controllers: ATLS50MA212D, ATLS500MA212D, ATLS1A212D, ATLS2A212D, and ATLS3A212D. Their input voltage can be between 4.75V to 16V, the output voltage can be from 1V to (VPS -1V), where VPS is the power supply input voltage. The maximum output voltage can reach 14V when powered by a 15V supply. They have 5 current capability versions, 50mA, 500mA, 1A, 2A and 3A, and are packed in 2 styles: DIP (Dual In Line) through hole package and SMT (Surface Mount Technology) package. The former has the part number with a suffix "D", for the latter the suffix is "S". For example: ATLS2A212D or ATLS2A212S. The main features are: high efficiency, high output power, small size, high current stability, low output noise, and wide modulation bandwidth. These controllers can be evaluated conveniently by using their evaluation board, ATLS212EV1.0. Since these series laser drivers can output high power and the high power lasers are often costly. In order to avoid making costly mistakes when evaluating this series of laser controllers, we have also developed a load assembly that can be used to emulate the expensive laser diodes for evaluating the laser controllers.
