Texas Instruments TPS543B22EVM Converter Evaluation Module (EVM)

Texas Instruments TPS543B22EVM Converter Evaluation Module (EVM) is designed to evaluate the TPS543B22. The TPS543B22 is a synchronous buck converter, integrating both power MOSFETs with a low drain to source resistance to minimize solution size and provide high efficiency at full load. The TPS543B22EVM uses fixed frequency advanced current mode control with low minimum on-time for high switching frequency to minimize solution size and achieve a fast transient response.

This evaluation module includes two designs with the Texas Instruments TPS543B22. The first design demonstrates the small printed-circuit-board areas that can be achieved when designing with the TPS543B22 regulator. The small area design fits within 275mm². The second design shows the high efficiency achieved when designing with the TPS543B22 regulator. The second design also includes jumpers that can easily evaluate the features of the TPS543B22.
