Texas Instruments  TPS40140EVM-003

The TPS40140EVM-003 evaluation module (EVM) is a single output two phase synchronous buckconverter. The EVM delivers 1.5 V at 32 A from a regulated 10.8 V to 13.2 V bus The module uses the TPS40140 dual or 2-phase stackable synchronous buck controller. The EVM is also stackable with the other EVM to construct a multiphase converter.

The TPS40140EVM-003 evaluation module demonstrates the TPS40140 in a typical regulated bus to low-voltage application while providing a number of test points to evaluate the performance of the TPS40140 in a given application.
