The Texas Instruments TPS40422EVM-091 evaluation module (EVM) helps designers evaluate the performance of the TPS40422 Dual Output or Multiphase Synchronous Buck Controller with PMBus. The EVM is designed to use a regulated 8.0Vdc to 14.0Vdc bus to produce two regulated outputs. One output is 1.2Vdc at a maximum of 20A load current, and the other is 3.3V at a maximum of 15A load current. The EVM also features the CSD86350Q5D NexFET™ Power Block FETs. The EVM is designed to demonstrate the TPS40422 in a typical dual output application.
