The Texas Instruments TPS82675EVM-646 is an evaluation board for DC/DC and AC/DC (Off-Line) SMPS (switched-mode power supply). This evaluation board applies a wide range of products, such as active power clamps, phase-to-ground fault detection, and voltage, current, and temperature protection. In addition, it can also be used to evaluate a variety of features, such as over-voltage, over-temperature, and current-backed over-current protection.

The TPS82675 is a high-efficiency, low-noise, low-distortion isolated DC/DC converter specifically designed for AC/DC and DC/DC applications. It offers a wide input voltage range of up to 800 volts and a high-efficiency output of up to 97% efficiency. The onboard trimming circuits enable precise control of the voltage and current across the load. The board also features an extended control area for board-specific settings, as well as monitoring and control circuitry for motor control applications.

The working principle of this board is based on the hysteresis principle. In a hysteresis topology, a reference voltage drives two comparators. The output of one comparator turns the hysteresis switch on and the output of the other comparator turns the hysteresis switch off. The hysteresis control provides a stable output voltage, even in the presence of noise and transients. The hysteresis loop also reduces the ripple and transient noise in the output voltage by maintaining a constant switching frequency.

TPS82675EVM-646 offers excellent protection features for a wide variety of load conditions and misapplication protection. It supports over-voltage protection, over-current protection, and current-backed over-current protection. In addition, the board also provides open-loop, soft-start, and under-voltage lock-out protection. The board also provides several additional monitoring features, such as line status, ripple, and output voltage.

The TPS82675EVM-646 evaluation board can be used in many areas, such as in industrial applications, datacom telecommunications, server and storage, and medical systems. Its modular design makes it easy to install and use. In addition, it is a cost-effective solution for DC/DC and AC/DC applications. With its high-efficiency and safety features, the board quickly and easily meets the requirements of a wide range of power system applications.
