TEA1721ADB1062,598 is a highly reliable, low cost evaluation board specially designed for both offline and online DC/AC and AC/DC switching power supply applications. It comes with several features that make it suitable for a variety of power applications, including DC/DC low voltage and AC/DC offline, high voltage, and open-loop or regulated applications. It can be used as a building block in switching power supplies, motor control and lighting systems, and many other industrial and consumer applications.The TEA1721ADB1062,598 is powered by a single-phase bridge rectifier and can deliver up to 10 A of current without external components. It has a wide range of switching frequency (from 30 - 80 kHz) and is ideal for either a single-ended or a balanced full-bridge configuration. The TEA1721ADB1062,598 also includes power factor correction and protection features such as current limit, overvoltage, and overcurrent protection, as well as over temperature protection.This evaluation board has a wide range of input voltage of 85 – 265 V AC, a 7 – 95 V DC output voltage range, and an adjustable output current limit from 0.2 – 5 A. It supports both single and dual outputs, and its output voltage is adjustable with a precision of up to 0.01V. The board is also protected against overcurrent conditions, overvoltage, and undervoltage, as well as over temperature conditions. It should be noted that the board does not have any EMI filtering or EMC protection built in.The TEA1721ADB1062,598 is suitable for a variety of applications due to its wide operating conditions and fault protection. This makes it an ideal solution for a variety of power applications such as low-voltage DC/DC, high-voltage AC/DC, and open-loop/closed-loop and regulated applications. It can also be used in motor control and lighting systems, as well as industrial and consumer applications. Its low cost, wide range of features, and ability to deliver high current make it a valued tool in any type of power electronics design.The working principle of the TEA1721ADB1062,598 is based on a full-bridge rectifier topology with a single-phase AC input. A full-wave rectifier works by rectifying the AC voltage at the input, which is then applied to the power supply’s primary side. A transformer then converts the rectified voltage from the primary to the secondary side, transforming it to a regulated DC output with a predetermined voltage. The output voltage can be adjusted by changing the primary input voltage.The TEA1721ADB1062,598 evaluation board also has an integrated logic bridge controller, which is responsible for monitoring the input current and the output voltage. The bridge controller communicates with other components within the system and also provides control signals to the primary and secondary stages in order to control the output voltage. The primary stage is responsible for adjusting the output voltage, while the secondary stage provides protection against overvoltage, overcurrent, and over temperature conditions. In conclusion, the TEA1721ADB1062, 598 evaluation board is a great solution for both DC/DC and AC/DC switching power supply applications. It offers a wide range of features that make it suitable for a variety of applications, including but not limited to DC/DC low voltage and AC/DC offline, high voltage, and open-loop or regulated applications. Its low cost and ability to deliver high current make it a valuable tool in power electronics design.
