TPS56221EVM-579: 1V @ 25A, 8 ~ 14V in


The TPS56221EVM-579 evaluation module (EVM) is a synchronous buck converter providing a fixed 1.0 V output at up to 25 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 TPS56221 High-Current Synchronous Buck Converter with integrated MOSFETs.

The TPS56221 integrates TI’s high performance controller technology with TI’s industry leading MOSFET technology in a standard QFN package to meet the demands of modern, high-current, and space constrained applications.
