8.1 Application Information

The TPSM64406 synchronous buck module requires only a few external components to convert from a wide range of supply voltages to an output voltage at an output current up to 3-A per single phase output and 6-A for two phase output. To expedite and streamline the process of designing a TPSM64406-based regulator, a comprehensive TPSM64406 quickstart calculator tool is available by download to assist the system designer with component selection for a given application.
