Description

This reference design details a power management circuit that is capable of sourcing and sinking current for driving a thermoelectric cooler (TEC) to control the temperature of sensitive devices: like laser diodes or sensors. It supports a small solution based on the integrated TPS63070 buck-boost converter: requiring only a few external components. With a simple high impedance analog voltage input to control the current flowing through the TEC: the converter can be used as a power solution for a microcontroller based temperature control system.
