In the field of analog electronics, it is very difficult to be well-known analog technology company. ATI inputs great efforts and time into developing new products, laser drivers, tec controllers, smt component kits. Most popular product of ATI is laser driver. Today I will introduce one high voltage constant current laser driver, whose part No. is ATLS12A216. It is a great laser driver that is popular among customers. As for the reasons, which can be concluded as high voltage, constant current, 12A output current and compact size.
Please take a look at the physical photo of this laser driver:
This laser driver, ATLS12A216, is an electronic module that has all the valuable and important, but often difficult to achieve simultaneously, features: wide input and output voltage range, high output current capability, high efficiency, low output noise (but it has an output 4mVp-p ripple voltage at 700kHz), wide modulation bandwidth, and small size. The wide output voltage range, 0.8V ~ 0.8VVPS, allows driving one or multiple serial laser diodes at the same time, for up to 12A well controlled current at high efficiency. The extremely low noise between DC ~ 20kHz and low DC current drift make it ideal for driving diode pumped single mode laser diodes to achieve mode-hop-free and narrow optical wavelength drift, thus, long coherent length.
