It operates from 3 to 12V, so is compatible with Li+ battery operation. It can be configured as two totally independent 250mA drivers or a single 500 mA driver. Compatible with Type A or B laser diodes. 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. Small Package (0.75” x 0.45” x 0.255”) Low Cost Brownout Protection 12-pin, SMT package, Reflow Compatible Slow Start Laser Diode Protection Drive Up to 500 mA Output Current Can be configured as two 250mA drivers Voltage Controlled Setpoint TTL Compatible Shutdown Pin Adjustable Current Limit on Eval boards Adjustable Current Range Output 500 kHz sinewave Constant Current Bandwidth (100kHz square wave) 图1.FL500方框图图2.单电源两个独立驱动器应用电路(VS = VDD). 图3.并联用作单个驱动器应用电路图4.多个FL500并联应用电路图 FL500 Laser Diode Driver Evaluation Board Use the FL591FL Evaluation Board to rapidly prototype a laser diode control system using the cutting edge technology of the FL500 Laser Diode Driver. Onboard switches, connectors, and trimpots make configuration and operation simple. Input and output cables are included. Operate the FL500 as two independent 250 mA channels or in parallel as one 500 mA driver. Switches set operation in either constant current (CC) or constant power (CP) mode. A trimpot sets the laser diode forward current limit. The input cables allow easy connection to your power supply and monitoring equipment while the output cables quickly connects to your laser diode and monitor photodiode. Operates A or B type Laser Diodes Configure as two independent 250 mA output channels or one 500 mA driver. Constant Current or Constant Power Operation Adjustable Current Limit Enable/Disable Switch, and LED status indication Includes Input/Output Cable Set (18”) FL500 is Reflow Oven Compatible 图5.评估板FL591FL外形图图6.评估板FL591FL方框图图7.评估板FL591FL电路图
