Description

The TPS544B28RBHEVM is designed to provide a quick setup to evaluate the TPS544B28 in an RBH package and gain familiarity with the device. The TPS544B28RBHEVM is designed for a nominal 12V bus and to produce a regulated 1V output at up to 20A of load current. The TPS544B28RBHEVM is designed to demonstrate PMBus® functionality and different pin strap settings of the TPS544B28 with the help of different connectors and jumpers, while providing a number of test points and connectors to evaluate the performance of the device.
