Temperature window TEC controller is an electronic module with small package, which is designed for driving thermoelectric coolers (TECs) with high energy efficiency, high stability and zero EMI. This laser driver can stabilize temperature within pre-set temperature window range and it also provides interface ports for customers to set the desired object temperature (within 10 °C~ 40 °C), the maximum output temperature and compensation network.

ATW3A314D is a kind of temperature window controller, which has high efficiency, more than90%, as shown in the Figure 1. This type controller is designed for regulating the object temperature within the range of the pre-set temperature, so it can be used to monitor the actual object temperature.It is completely shielded, so there is no EMI. The switching frequency of this controller is synchronized to an external signal. There are two types of packages available for selection, DIP and SMT packages.
