Optocoolers Fulfill High Voltage Circuitry And Power Requirements

摘要

Nextreme Thermal Solutions announced the availability of its OptoCooler HV Series RoHS-compliant high voltage and high heat pumping thermoelectric coolers optimized for standard circuitry and power requirements. The OptoCooler HV14 operates at a maximum voltage of 2.9 V, andean pump 1.7 W of heat at 85°C in a footprint of 2.8 mm2. The module can create a temperature differential (DeltaT) of up to 51℃ between its hot and cold sides, making it suitable for the cooling and temperature control of optoelectronic devices such as laser diodes and high-brightness LEDs. The company's Thermal Copper Pillar Bump-an electronic device made from thin-film thermoelectric material embedded in flip chip interconnects used in electronic and optoelectronic packaging-acts as a solid-state heat pump and adds thermal management functionality locally on the surface of a chip or other electrical component. Nextreme reduced the size of the thermal bump by 75 percent, thereby increasing voltages by 300 percent and reducing current draw by the same proportion. The net result eliminates the need for special voltage conditioning and reduces the overall electrical current required to operate the device.
