Detailed Description
The LDD-1303 is a current source designed to precision-drive Laser diodes in continuous wave applications. Its power converter topology (buck-boost) allows for an output voltage smaller, equal, or larger than the input voltage. This enables the LDD to drive Laser diodes with up to 120 V compliance voltage from a single 48 V power supply. The LDD-1303 offers various safety features, including two inputs for Laser diode temperature monitoring.
The device can be fully digitally controlled, the firmware is upgradeable and various digital communications interfaces are available. A 0 - 10 V analog Input as well as a 0 - 10 V analog output are integrated. Additionally, Laser Power Control using a photodiode is possible using the on-board amplifier.
The LDD-1303 has been developed as a CW Laser diode driver but can also be used as a pulsed driver (350 µs). In series even higher output voltages can be achieved.
