The TPS92411EVM-002 Evaluation Board is a member of the multi-functional LED driver family of products. It features linear, dimmable and non-dimmable LED driver evaluation boards, providing a convenient platform for fast, easy, low-risk integration of energy-efficient high power LED lighting solutions. The TPS92411EVMS-002 Evaluation Board is for driving up to 10 Watts of an isolated non-dimmable LED system with an efficiency of up to 92%.

TPS92411EVM-002 is designed for use in both small-scale and large-scale LED applications such as outdoor and indoor lighting, automotive applications, architecture, and other energy-efficient lighting solutions requiring linear and dimmable operation.

The TPS92411EVM-002 evaluation board features a unique and comprehensive design that combines forward-converter with AC/DC or DC/DC rectifier and a resonant mode power stage. This combination results in a highly efficient LED driver platform, providing high performance, dimmable and non- dimmable LED solutions. As a result, the board supports a wide range of LED applications, including outdoor lighting, indoor lighting, and automotive lighting.

In terms of working principle, the TPS92411EVM-002 combines two stages, the power stage and the power factor regulator. The power stage serves as the main driver for the LED, while the power factor regulator balances the ripple in the system and provides a smooth light curve. On the power stage, the initial input voltage is first delivered to energy storage capacitor and then converted to a constant voltage and constant current, which further drives the LED load. The output current of the power stage is regulated by the power factor regulator, which also provides a smooth dimming. Then it passes to the power stage, a linear voltage ramp is created for dimming control.

In conclusion, the TPS92411EVM-002 offers industry-leading efficiency and performance for both linear and dimmable LED applications. The innovative design allows it to meet the most demanding design requirements, while providing a platform for fully optimized, low-risk integration of highly efficient high power LED applications. The board features a wide input voltage range, adjustable output current, and supports a variety of dimming modes, providing an easy-to-use and cost-effective solution for any new or existing LED lighting projects.
