Low Power TEC Driver Reference Design (PMP9759)

This reference design details a power management circuit which is capable to source and sink 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 a completely integrated 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 it can be used as a power solution for a microcontroller based temperature control system.

Возможности

Source and sink current capability to drive a TEC More than 1.5 A source current possible High impedance analog control input Less than 180 mm² required for the complete power solution Simple design, small BOM More than 90% efficiency over a wide operating range
