laser driver, ATLS500MA212DHS, is an electronic module that has all the valuable and important, but often
contradict features, simultaneously: Wide input and output voltage range, high
output current capability, high efficiency, low output noise (but it has a 4mVP-P
ripple voltage at 500kHz), wide modulation bandwidth, and small size. The wide
output voltage range, 0.1VVPS~ 0.9VVPS, allows driving one or multiple
serial laser diodes at the same time, for up to 500mA well controlled current
at high efficiency.
