The TPS53219EVM-690 evaluation module (EVM) uses the TPS53219. The TPS53219 is a small-size, single buck controller with adaptive on-time D-CAP™ mode control. It provides a fixed 1.1-V output at up to 25 A from a 12-V input bus. TPS53219EVM-690 also uses the 5-mm x 6-mm TI power block MOSFET (CSD86350Q5D) for high power density and superior thermal performance. The TPS53219EVM-690 is designed to use a regulated 12-V bus to produce a regulated 1.1-V output at up to 25 A of load current. The TPS53219EVM-690 is designed to demonstrate the TPS53219 in a typical low-voltage application while providing test points to evaluate the performance of the TPS53219.
