TPS65257EVM

The TPS65257EVM is a robust and compact evaluation module designed to provide a comprehensive platform for the evaluation of the TPS65257, a three-channel, unregulated, high current, synchronous, primary-side controller for off-line LED projects. The TPS65257EVM is an ideal tool for evaluating the features and performance of the TPS65257 device, as well as familiarizing users with its operation and programming.

The board features three separate, independent LED channels, each of which can be configured to drive up to 300 mA into a single LED string. The board itself can generate up to 5.8 W for its LED channels, making it suitable for a wide variety of lighting applications. The TPS65257EVM also has a wide input voltage range of 90 V to 265 VAC, making it suitable for applications running on virtually any mains voltage in the world.

The TPS65257EVM features an on-board split-inductor buck architecture. Thanks to this architecture, it is capable of providing high efficiency in a wide range of conditions, making it ideal for LED applications that require low power dissipation. The board also features an advanced, easy-to-program primary-side controller. This controller provides improved system accuracy, resulting in a more stable LED power output.

The module is also equipped with active loop compensation, allowing for higher system stability and better output control. This built-in active loop compensation also helps reduce EMI/RFI, enabling operation in noisy environments. Finally, the module supports a variety of programming options, including programming via I2C, SPI, PWM or manual programming.

The TPS65257EVM offers a wide range of features and is an excellent choice for evaluating and prototyping LED lighting projects. It provides a comprehensive platform for testing the features and performance of the TPS65257, making it an ideal tool for electrical engineers and designers who are looking for a complete solution for off-line LED projects.
