TEC Controllers

Thermo-Electric Coolers, also known as Peltier coolers, provide both cooling and heating by reversing current flow. ATI TEC controllers precisely regulate TEC current direction and amplitude to maintain stable temperature in demanding thermal control applications.

With more than 21 years of TEC controller design experience, ATI has developed a patented single-PWM output-stage architecture that improves power efficiency while reducing component count, PCB area, and system cost compared with conventional dual-PWM designs. ATI offers a broad range of TEC controllers for applications requiring high precision, high efficiency, compact size, and reliable long-term temperature regulation.
