Output Current LD 0.5 A; PCB Mount; Compatible with Type A & B Lasers  Wavelength Electronics’ FL500 series of component type surface mount laser diode drivers is ideal for driving low power laser diodes where low noise is critical. Low leakage current (150 µA) makes it ideal for driving most VCSELs. The FL500 series laser diode drivers operate from 3 to 12 V, so they are compatible with Li+ battery operation. FL500 drivers can be configured as two totally independent 250 mA drivers or a single 500 mA driver and are compatible with Type A or B laser diodes. Because of their small size and low noise, the series is often used in handheld devices and spectroscopy systems. The base unit operates in constant current (CC) mode. The only external components required are a power supply, an analog control voltage, your laser and optional filtering circuitry. For additional features, including current limit and photodiode feedback for constant power operation, use the FL591FL evaluation board with controller. Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard products can be easily modified to meet your application requirements. Get in touch with the AMS Technologies laser diode driver experts to discuss your customized solution!
