This laser driver, ATLS3A201D, is an electronic module designed for driving diode lasers by an up to 3A constant current with high efficiency, low noise, high stability, high reliability, zero EMI, and small package. It provides these functions: laser current control, laser current monitoring, over temperature protection, loop good indication, synchronization with an external clock to eliminate beating interference with the other switch mode device, soft start, and shut down.

It comes with a high stability low noise 2.5V voltage reference. This voltage can be used by a POT (Potentiometer), or a DAC (Digital to Analog Converter) to set the voltage on the LIS pin for programming the output current, and, at the same time, by an ADCs (Analog to Digital Converters) to measure the voltage on the LIO pin for monitoring the output current.


Power Supply Voltage Range: 3.1V ~ 6V
High Efficiency: ≥90%
Maximum Output Current: 3A
Current Output Noise: <100µA@0.1Hz ~ 10Hz
High Stability: ± 8mA@3A for entire temperature
Compact Size
Fully shielded
100 % Lead (Pb)-free and RoHS Compliant
