Drive Laser Diodes and VCSELs to 3 A with NO Leakage Current

The highly popular WLD3343 Precision Laser Diode Driver has been upgraded for higher output current, lower noise, and no leakage. It provides up to 3 A output with excellent current stability in a compact 14-pin DIP package. The WLD3343 Series is ideal for a wide variety of high performance electro-optical instrumentation. The upgraded WLD3393 Evaluation Board now supports the full output current range of the WLD3343 for fast system design.

Available in standard and low noise versions, the WLD3343 is an analog circuit for space-constrained designs that supplies up to 2MHz modulation bandwidth, current limiting, and Constant Current or Constant Power operation with any laser diode configuration. To protect your laser diode and ensure reliable performance, safety features including slow start, voltage-controlled setpoint, TTL-compatible shutdown, and over-temperature shut-off have been incorporated into the design.

The WLD3393 operates from a single supply input and is compatible with all standard laser diode configurations. Onboard switches, connectors and trimpots make fine-tuning of the laser diode forward current and limit easy and accelerate product design.

Our high performance specifications are supported by a team of experienced sales and design engineers and a top-notch manufacturing facility.
