Low-noise SLED and LD driver boards control unstable supply voltages
EXALOS driver boards from AMS Technologies (Martinsried, Germany) are highly stable, ultra-low noise solutions for both OEM and R&D applications, and allow changing of the light source and control key parameters via a display. The driver boards are especially designed to handle noisy, spiky or unstable supply voltages. The multi-layer PCB design with shielding ground layers allows for the co-existence of a highly efficient switched-mode temperature controller (TEC) with a low-noise linear drive current controller in a compact form factor. A heat-spreading thermal design reduces hot spots for stable operation at high ambient temperatures. Operating temperatures range from -20° to 65°C.
