TPS65266EVM-686

The TPS65266EVM-686 is an evaluation module designed for the evaluation of TPS65266, which is a high-efficiency low-EMI DC/DC &AC/DC (Off-Line) SMPS (Switched Mode Power Supply). This evaluation module is a fully functional converter that can be used to evaluate and design isolated DC-DC converter applications in the 48 V – 65 V input voltage range. The primary side MOSFET operating frequency is 700 kHz and the few components required allow easy prototyping of the evaluation board. This evaluation module features a high accuracy current limit, over-temperature protection, and built-in monitoring and control functions.

The TPS65266EVM-686 is an advanced evaluation module that can be used to evaluate various power management options such as load shedding, unprotected start-up, over-temperature protection, and over-current protection. It offers a user-friendly graphical user interface (GUI) for controlling the converter operations and monitoring the feedback parameters. It also supports optional isolated programming via a serial peripheral interface (SPI) and USB interface. This evaluation module is available in two versions: TPS65266EVM-686 and TPS65266EVM-686.

In terms of application fields, the TPS65266EVM-686 is an ideal solution for industrial applications and mission-critical equipment. It is specifically designed for applications such as cloud computing, data centers, high-power storage systems, industrial computers, painting systems, and telecommunications systems. It is also suitable for automotive applications such as automotive infotainment systems, power steering systems, and hybrid vehicles.

In terms of working principles, the TPS65266EVM-686 is based on the high-efficiency isolated DC/DC SMPS topology. It consists of an input stage, a switching stage, and an output stage. During normal operation, incoming AC voltage is rectified and filtered to generate a low-voltage DC signal. This DC signal is then converted to a high-frequency AC signal through an isolated PWM (Pulse Width Modulation) controller. The high-frequency AC signal is then used to turn on and off the power MOSFETs in order to generate the required DC voltage on the output side. The output voltage can be adjusted via the external feedback resistor.

Overall, the TPS65266EVM-686 is a fully functional evaluation module with easy prototyping and an intuitive GUI for tuning and monitoring. It is suitable for industrial, mission-critical and automotive applications as well as low-power storage systems, telecommunications systems, and power steering systems. It offers reliable and precise control of the SMPS system through its efficient design and high-accuracy current limit, over-temperature protection, and built-in monitoring and control functions.
