TPS53310EVM-755 evaluation board is an important industrial product for AC/DC (off-line) SMPS applications. It is a single-chip DC/DC step-down converter and is used to provide reliable power supplies for equipment such as 3D printers, medical imaging systems, IoT panels, digital video recorders, and many other types of products. This versatile product is capable of generating up to 20.0V output voltage and up to 150mA of output current, making it an ideal choice for many applications.

The board is based on the TPS53310EVM-755 chip, which is a non-synchronous buck converter. It contains a buck-boost pre-regulator, integrated +/- 12VINPI switch, integrated dc/dc controllers, and a 0.6mm thick copper PCB specifically designed for the non-synchronous buck converter design. In addition, there are two external resistors and one inductor that are used for the design of the power supply.

The integrated resistor network provides better system stability than the external one and it is easily adjustable based on the target output power. The two non-synchronous buck switches, which are connected to the output, significantly reduce the leakage current and provide excellent efficiency. The TPS53310EVM-755 evaluation board also offers an optimal thermal design with low profile, which is designed to reduce the operating temperature and maximize its efficiency.

The TPS53310EVM-755 evaluation board features a wide input range with programmable outputs, enabling excellent performance under a wide range of operating conditions. The power up sequencing allows the user to adjust the control signals and the output voltage to the target level as desired. In addition, the pre-regulator circuit ensures fast response time and low power consumption.

The integrated controller further helps to reduce system costs and improve efficiency. The integrated feedback amplifier allows for setting the output voltage even during light load conditions, while the PWM comparator ensures fast transient recovery. When compared with other non-synchronous buck converters, the TPS53310EVM-755 board has an improved efficiency up to 98%, which provides a longer operating time and reduces the total power consumption.

Overall, the TPS53310EVM-755 evaluation board is an excellent choice for applications requiring robust AC/DC (off-line) SMPS. Its wide input range allows for efficient operation under a variety of conditions and its temperature optimized design helps to increase the system reliability. Additionally, its integrated feedback amplifier and PWM comparator enable more accurate control and fast transient recovery, while its integrated buck switches significantly reduce power consumption and further improve the system efficiency.
