Product Overview
The ATLS14M5V3R5AS is an ultra compact, low profile, fully molded constant current laser diode driver for driving laser diodes up to 3.5A with low noise and high efficiency. It operates from a 3.1V ~ 6V power supply. It is a surface mount part, 14.0mm × 14.0mm × 2.1mm, with a bottom thermal pad for heat sinking. Output noise is 3.97µAP-P (0.1Hz ~ 10Hz).
It provides laser constant current control, laser current monitoring, over current and thermal protection, loop good indication, laser diode status indication, soft start, and shutdown. A low noise 2.5V reference output can be used to set the output current, or to feed ADCs and DACs. The driver is suitable for applications including DPSSL, EDFA, Fiber Laser, Direct Diode Lasers.
