Maiman Electronics’ SF8XXX series of laser diode drivers and TEC temperature controllers are suitable for driving fiber coupled laser diodes in a butterfly package with 10 or 14 pins. SF8XXX series drivers are available with pinouts for Type 1 (Pump) or Type 2 (Telecom, SF8XXX-T) butterfly laser diodes.

The SF8XXX drivers include highly stable (±0.01 A) current sources for the laser diode and a thermoelectric Peltier cooler (TEC). The integrated temperature controller keeps the temperature on the Peltier element with high precision within ±0,01 °C.

The laser diode driver circuit of the SF8XXX series is a non-isolated low drop-out (LDO) regulator with constant current output, producing current with high stability and low ripple. The TEC driver circuit is a non-isolated DC/DC converter, producing low current ripple.

Additional features of the SF8XXX series include an adjustable TEC output current limit and an integrated self-adjusting PID controller, providing optimal temperature regulation. All SF8XXX can be controlled by analog signal or digital signals and switches on the board.

The SF8xxx series drivers are housed in a 61 × 101.6 mm enclosure with aluminium base plate to aid thermal dissipation from the laser diode. SF8xxx series drivers can be mounted on any surface that is thermally conductive enough to dissipate the laser diode’s power loss.

The laser diode mount is located on the board – either with landing pads for soldering a butterfly laser diode directly into driver board or with an integrated mounting Azimuth socket for butterfly packaged devices (-ZIF types).
