TPS40400EVM-351 Datasheet PDF - TI

●The TPS40400EVM-351 is an evaluation module, which is fully assembled and tested circuit for evaluating the TPS40400 PMBus synchronous buck controller in a typical single output application. The evaluation module is designed to use a regulated 8Vdc to 14Vdc bus to produce a regulated output of 1.2Vdc at a maximum of 20A of load current. The evaluation module features the CSD16325Q5 and CSD16404Q5A NexFET Power FETs. If a designer wants to communicate with this evaluation module from a Windows based PC, a separate USB Interface Adapter evaluation module is required. The USB to GPIO Adapter serves as an interface adapter or a bridge between a host PC (IBM compatible) and one or multiple slave devices via a standard type-A to mini-B USB cable.
