Abstract
A highly efficient thermoelectric cooler controller for temperature stabilization. The circuit comprises a temperature sensor and a thermoelectric cooler, both in thermal communication with a component to be temperature stabilized. The circuit further comprises a power amplifier electrically coupled to the thermoelectric cooler. The power amplifier is employed as a controlled current source to efficiently supply current to the thermoelectric cooler when maximum cooling is required.
