Diode laser driver
ATLS500mA212D is one of high voltage constant current laser driver series. This series laser drivers are designed for driving high voltage diode laser or multiple diode lasers at the same time.
ATLS500mA212D laser driver comes with a maximum output current of 500mA. The power supply voltage ranges from 4.5V to 16V. The efficiency is up to 80%, higher than other high voltage laser drivers in the market. There are more features, such as low output noise (< 10µA@0.1Hz~10Hz), wide modulation bandwidth (DC ∼ 10 kHz), compact size (25.4×20×5 mm), both DIP and SMT packages available, and 100 % lead (Pb)-free and RoHS compliant.
This high voltage laser driver has a protection circuit inside, which is aimed to shut down the output stage and force the laser driver into standby mode automatically when the temperature exceed 120°C.
Besides ATLS500mA212D, there are also three more high voltage laser drivers, namely,
ATLS1A212D,
ATLS2A212D, and
ATLS3A212D, with the maximum output current of 1A, 2A, and 3A respectively.
