User manual for the FL591FL Evaluation Board, used to prototype laser diode control systems with the FL500 driver.
This document provides step-by-step instructions for configuring and operating the FL591FL Evaluation Board with the FL500 Laser Diode Driver. It covers setup for individual or parallel operation, constant current or constant power modes, power supply connections, and laser diode current limit adjustments. The board includes onboard switches, connectors, and trimpots for easy configuration. It is designed for prototyping laser diode control systems using the FL500 driver.
The manual includes schematic diagrams, safety notes, and operational guidelines to ensure safe and effective use of the board. It also provides information on compatible laser diode types (A and B) and how to simulate laser diode loads for initial testing without risking damage to expensive components.
| Operating Mode | Constant Current (CC) or Constant Power (CP) |
|---|---|
| Current Limit Adjustment | Adjustable via LIM1 and LIM2 trimpots |
| Laser Diode Compatibility | Type A or B laser diodes |
| Power Supply Voltage | 3 to 9 V DC |
The FL591FL supports only Type A or B laser diodes. Type C is not supported.
With power removed, connect the 3-wire output cable to the laser diode. Use LDA for laser diode anode, PDA for photodiode anode, and LDC for laser diode cathode.
