Mouser is now stocking UltraTEC UTX thermoelectric coolers (TECs) from Laird Thermal Systems and the LTM4663 ultra-thin μModule TEC regulator from Analog Devices. Together, the advanced TEC devices make the core of a temperature feedback control loop design, presenting a reliable solution for employment in industrial laser applications, optical modules, and optical networking systems, and also medical diagnostics, laser projectors, and LiDAR systems.

The ADI LTM4663 μModule TEC regulator includes a TEC controller, switching regulator, linear power stage, inductor, and support components in a compact 3.5mm x 4mm x 1.3mm LGA25 package. The device’s ultra-thin package permits it to be placed on the back side of a PCB in optical modules, even in the most rigorous form factors such as QSFP-DD where 1.4mm is the maximum height possible. The TEC regulator runs over an input voltage range of 2.7V to 5.5V and features two self-correcting, auto-zeroing amplifiers to serve as a temperature feedback control loop and thermistor input amplifier. The regulator supports versatile use cases, allowing developers to independently program maximum cooling and heating currents, as well as the maximum TEC voltage.

The Laird Thermal Systems UltraTEC UTX TECs are assembled using next-generation thermoelectric material, delivering key improvements in efficiency and temperature differential, boosting cooling capacity by up to 10%. The TECs offer high cooling capacity, making them an excellent choice for both laser cooling and laser projection.


When used together, the regulator and TECs offer an efficient thermal management solution for laser and optical applications. The regulator enables designers to manage the temperature feedback control loop, while the TECs provide the cooling function and heat pump needed for reliable temperature control.
