Hi,
I'm trying to drive PLT3 520D for surface patterning applications. The laser needs to run for 1 to 5 minutes at a time at an output power of 50 to 100 mW without pulsing.
I'm hoping to control the output power and on/off state using some serial connection (UART/SPI/I2C/etc.) by a microcontroller but I can also work with analog voltage signaling from a DAC. However, most drivers discussed on this website are pot-controlled and not applicable.
The device will not be battery powered but the supply voltage will likely be between 5 to 10V (flexible on the choice of power supply, but would prefer a buck/boost configuration for the driver)
I would appreciate any design tips and suggestions for the driving circuitry!
The datasheet for PLT3 520D is attached below.
