This laser driver, ATLS25A219D, 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 10mVp-p ripple voltage at 500kHz), wide modulation bandwidth, and small size. The wide output voltage range, allows driving one or multiple serial laser diodes at the same time, for up to 25A well controlled current at high efficiency. The extremely low noise between DC 0.1Hz ~ 10Hz and low DC current drift make it ideal for driving high current laser diode arrays. Because of the high efficiency, the build-in small heat sink is sufficient to dissipate the heat generated by the driver, no additional heat sink is needed. The fully shielded case blocks all
the incoming and outgoing EMIs (Electro-Magnet Interferences). Therefore, this laser will not interfere other surrounding electronics, nor will be interfered by them. The small package saves valuable PCB space in laser systems.
