Page 2: Introduction
The TPS53515EVM-PWR587 is designed for a regulated 12-V bus to produce a regulated 1.2-V output at up to 12 A of load current. The TPS53515EVM-PWR587 is designed to demonstrate the TPS53515 device in a typical low-voltage application while providing a number of test points to evaluate the performance of the TPS53515 device. -
