Evaluation and Demonstration Boards and Kits provide engineers with the tools they need to quickly test and prototype systems in a wide variety of development applications. The TPS22970EVM is one such board, designed for the revolutionary Texas Instruments TPS22970 Secondary Side Synchronous PWM Buck Controller. This device offers advanced features in its 9.5-ns transient response, allowing for increased efficiency and lower power losses in power control. As such, the TPS22970EVM enables engineers to develop advanced and innovative solutions for power control applications.

The TPS22970EVM features a main board with integrated power supply and four output channels, two of which are enabled for direct connection to an external device. The main board consists of a TPS22970 device and two TPS22976B Synchronous Buck Controllers. The board is connected to an external power supply, and while the external power supply is not included in the EVM package, a wide range of compatible supplies are available. Users will find that the accompanying Control and Measurement Suite allows for measurement of converter parameters over a range of load conditions.

The TPS22970EVM is an ideal development board for a variety of applications, such as high-power motor drive systems, voltage-regulated power supplies, AC/DC power adapters, battery chargers, and low-voltage isolated systems. Its highly reliable operation is backed by Texas Instruments’ expertise in high-efficiency power solutions. As a result, users have the assurance that their applications are supported by best-in-class solutions.

The TPS22970EVM features a wide range of operational features designed to facilitate development and debugging. Thanks to its comprehensive protections, the device and its applications are reliably protected from over-temperature, over-current, and short-circuit conditions. Additionally, the device is protected against electro-static discharge and surge conditions.

At the heart of the TPS22970EVM is a comprehensive control loop that ensures optimal control. This provides the user with optimal accuracy in switching control, ensuring consistent efficiency and minimized energy loss. The board also features Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) for improved output-power quality, which helps to reduce inrush current and other transient effects that could otherwise adversely affect the performance of the application.

The TPS22970EVM is connected to the external power supply via two input terminals, and the voltage level sensed by the device is provided as an analog input. In this way, the user is able to set the VO output level while keeping the same power efficiency as expected at the beginning of the design cycle. Further, the device provides a range of advanced features, such as dynamic voltage scaling, adaptive compensation, and PWM-overvoltage protection, to ensure remarkable output accuracy.

The TPS22970EVM support a wide variety of operating modes, including Constant-Voltage Mode, Constant-Current Mode, Standby Mode, and Power-Saving Mode. In addition, an integrated EMI filter reduces the number of external components required, making the device more cost-effective for users. Finally, the board makes use of Texas Instruments’ propriety Smart Combat technology, which helps to further reduce output-voltage droop under load, as well as to extend the life of the device.

For engineers looking for a high-performance, reliable solution for their power control applications, the TPS22970EVM provides the right combination of features and performance. Thanks to its advanced control loop, an extensive library of integrated features, and high-efficiency operations, the TPS22970EVM supports faster development cycles and higher integration levels for optimal performance.
