DESCRIPTION
FL500
500 mA Laser Diode Driver
FL591FL
500 mA Laser Diode Driver and Board
FLEXIBILITY YOU NEED
The FL500 Laser Diode Driver comes in a small SMT
package that is reflow process compatible.
The FL500 is ideal for driving low power laser diodes. It
operates from 3 to 12 V, so it is compatible with Li+ battery
operation. This makes it practical for handheld devices.
It can be configured as two totally independent 250 mA
drivers or a single 500 mA driver. It is compatible with
Type A or Type B laser diodes.

EASY INTEGRATION
The FL500 allows for quick and easy operation in Constant
Current (CC) mode. For simple CC mode operation the
only components that are 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
with the
driver board.
LEADING EDGE APPLICATIONS
The FL500 is commonly used in hand-held, portable, and
space constrained applications. Small and light weight,
the FL500 is ideal for airborne applications, spectroscopy
systems, and the dual-channel output is perfect for
sighting-and-detection applications.
