TPS56121EVM-601: 1V @ 15A, 8 ~ 14V in

Summary

The TPS56121EVM-601 evaluation module (EVM) is a synchronous buck converter providing a fixed 1.0-V output at up to 15 A from a 12-V input bus. The EVM is designed to start up from a single supply; no additional bias voltage is required for start up. The module uses the TPS56121 High-Current Synchronous Buck Converter with integrated MOSFETs.

The TPS56121 integrates TI’s high performance controller technology with their industry leading MOSFET technology in a standard QFN package to meet the demands of modern, high-current, and space constrained applications.
