连续波激光器的平均电源控制器 Continuous Wave Laser Average Power Controller
Product Details
The ADN2830 provides closed loop control of the average optical power of a continuous wave CW laser diode LD after initial factory setup. The control loop adjusts the laser Ibias to maintain a constant Back Facet Monitor Photo Diode MPD current and hence a constant laser optical power. The external PSET resistor is adjusted during factory set up to set the desired optical power. Programmable alarms are provided for laser fail end of life and laser degrade impending fail.
The ADN2830 operates from a single power +5 V supply. It is available in 5mm x 5mm LFCSP-32 Lead Frame Chip Scale.
