Warsash Scientific have released the re-engineered FL500 low noise laser diode driver to integrate with higher temperature RoHS-compliant manufacturing processes. It is now compatible with reflow processing less than 250°C. This surface mount chip is suitable for OEM instrumentation.
The FL500 low noise laser diode control driver can be configured either as two independent 250mA drivers or as a single 500mA driver. The FL500 low noise laser diode control driver can run on a +3V Lithium-ion battery or up to a +12V power supply. Its small size, low noise and modest power requirements make the FL500 low noise laser diode control driver suitable for handheld precision laser instrumentation.
For additional features, including current limit and photodiode feedback for constant power operation, the FL500 low noise laser diode control driver can be used with the FL591 evaluation board.
