Devices deliver thermal management solution for lasers

Together, the advanced TEC devices form the core of a temperature feedback control loop design, providing a reliable solution for use in industrial laser applications, optical modules, and optical networking systems, as well as medical diagnostics, laser projectors, and LiDAR systems.

The ADI LTM4663 μModule TEC regulator integrates a TEC controller, switching regulator, inductor, linear power stage, and support components in a compact 3.5 mm × 4 mm × 1.3 mm LGA25 package.

The device's ultra-thin package allows it to be placed on the back side of a PCB in optical modules, even in the most stringent form factors such as QSFP-DD where 1.4 mm is the maximum height available.

The LTM4663 TEC regulator operates over an input voltage range of 2.7 V to 5.5 V, 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 ideal choice for both laser cooling and laser projection.

When employed together, the Analog Devices LTM4663 regulator and Laird Thermal Systems UltraTEC UTX TECs provide an efficient thermal management solution for laser and optical applications.

The LTM4663 regulator allows designers to manage the temperature feedback control loop, while the UltraTEC UTX TECs deliver the cooling function and heat pump necessary for reliable temperature control.
