Description
The TPS53310EVM-755 uses a regulated 3.3-V or 5-V bus to produce outputs at up to 3 A of load
current. The output is 1.5-V master and 1.2-V slave. The TPS53310EVM-755 is designed to demonstrate
the TPS53310 in a typical low-voltage application while providing test points to evaluate the performance
of the TPS53310.
