Page 3: Introduction
The TPS53313EVM-078 is designed to use a 12-V voltage rail to produce a regulated 1.2-V output with up to 6-A load current. The TPS53313EVM-078 is designed to demonstrate the TPS53313 in a typical Point-Of-Load (POL) application while providing a number of test points to evaluate the performance of the TPS53313. 2.1 Typical Applications •... -
