Introduction
The TPS40131EVM evaluation module (EVM) is a single output two-phase synchronous buck converter.
The EVM delivers 1.5V at 40A. The module uses the TPS40131 Synchronous Buck Controller.
TPS40131EVM is designed to use a regulated 10.8V to 13.2V bus to produce a high current, regulated
output. The output is capable of supplying up to 40A of load current. The TPS40131EVM is designed to
demonstrate the TPS40131 in a typical regulated bus to low-voltage application while providing a number
of test points to evaluate the performance of the TPS40131 in a given application.
