20A CW Laser Diode Driver

BRM-6103
20A CW Laser Diode Driver

The BRM-6103 is a versatile laser driver controller featuring continuously tunable drive current (up to 20A max) and support for three operating modes:

1. Continuous wave (CW)

2. Analog input control

3. Optical power control (APC)

It offers an external I/O interface for a photodiode and NTC temperature sensor, supporting precise monitoring and protection. It boasts high precision, low ripple, and flexible control, making it well-suited for high-power laser diode driving, optical power stabilization, industrial lasers, and scientific research. The compact controller ensures stable performance in demanding applications.
