The TPS40400EVM-351 evaluation module (EVM) uses the TPS40400. The TPS40400 is a synchronous buck controller that operates from a nominal 3.0-V to 20-V supply. This controller is an analog PWM controller that allows programming and monitoring via the PMBus interface.
The TPS40400EVM-351 is designed to use a regulated 12-V bus to produce a regulated 1.2-V output at up to 20 A of load current. The TPS40400EVM-351 is designed to demonstrate the TPS40400 in a typical low-voltage application while providing a number of test points to evaluate the performance of the TPS40400.
