The TEA19031AQT/1J is an adjustable AC/DC switching converter designed for use in offline isolated power supplies and battery chargers. Specifically designed for low output voltage systems, its features include a universal input voltage (85VAC - 264VAC), auto-restart, low input power consumption and a power factor correction (PFC) function. It is suitable for a wide range of AC/DC power supply applications, including appliance control systems, industrial control systems, and HVAC systems.

The TEA19031AQT/1J operates by regulating an output voltage. The input voltage is rectified to a fixed DC value, which is then switched at a frequency determined by the control circuit. The output voltage is monitored and controlled by the feedback circuit, including a voltage reference. When the output voltage drops, the control circuit increases the rate of the switching frequency, causing the output voltage to rise. The output is also regulated by a current limiter and a thermal shutdown circuit.

The TEA19031AQT/1J features an adjustable switching frequency, enabling it to be optimized for different power requirements. This coupled with the low input power consumption and PFC function makes it an ideal solution for low voltage applications requiring an efficient, reliable power supply. The auto-restart feature also provides added protection against power supply failure or interruptions.

In addition, the TEA19031AQT/1J can be used as an analysis tool for development and testing purposes. By monitoring the output voltage, input voltage and current, and frequency of the control circuit, developers can more accurately assess the performance and efficiency of their system. This can help to prevent overload and minimize losses due to energy waste.

The TEA19031AQT/1J is a versatile, high efficiency AC/DC switching converter suitable for a range of applications. With its adjustable switching frequency, low input power consumption, PFC function and auto-restart feature, it is well-suited to providing reliable, efficient power in low voltage applications.
