TEC controller is widely applied in temperature control system these years. TEC controller is also called peltier controller, which can regulate the temperature of the thermal load, i.e. cool down or heat up, depending on the current direction through the two terminals of the TEC.
Multiple types of TEC controllers are provided in Analog Technologies, Inc. We are going to focus on one TEC controller,
TEC5V4A-D It features high efficiency, higher than 90%. The maximum output current is 4A. With high reliability and stability, this TEC controller can drive TECs to regulate the object temperature.
There is a physical photo of this TEC controller in Figure 1. As we can see, it has a compact size: 20×25.6mm and 16 pins with different functions. The TEC controller is packaged in a 6 sided metal enclosure, which prevents the controller from interfering with other electronics.
This TEC controller has two compensation network versions; one is with internal compensation network and the other without it. The latter TEC controller can use an external compensation network, which is composed of two capacitors and three resistors.
