High Efficiency 14A Synchronous Buck Converter with
Eco-Mode™
The TPS53319EVM-136 is designed to use a regulated 12V bus to produce a regulated 1.5V output at up
to 14A of load current. The TPS53319EVM-136 is designed to demonstrate the TPS53319 in a typical low
voltage application while providing a number of test points to evaluate the performance of the TPS53319.
