Tiny thermoelectric cooler improves high-voltage support
Microscale thin-film device operates at 2.9 V to meet LED cooling needs
The OptoCooler HV14 is the first in a series of thermoelectric coolers that support high-voltage applications in optoelectronics and telecommunications industries. The cooler helps remove existing voltage and current barriers standing in the way of thin-film thermoelectric integration in electronics.
The cooler operates at a maximum voltage of 2.9 V and provides 1.7-W power dissipation (at 85°C) from a 2.8-mm2 footprint. The device can create a temperature differential of up to 51°C between its hot and cold sides, suiting the cooling and temperature-control needs of devices such as laser diodes and high-brightness LEDs.
The RoHS-compliant cooler uses the company’s thermal copper pillar bump technology. Thermal bumps act as solid-state heat pumps and add thermal management functionality locally on the surface of a chip or other electrical component. Thermal bumps have been reduced in size by 75% — increasing voltages by 300% — and reducing current draw by the same proportion. (Contact Karl von Gunten for pricing and availability.)
