1 Description

The TPS53355EVM-743 is designed to use a regulated 12-V bus to produce a regulated 1.5-V output at up to 30 A of load current. The TPS53355EVM-743 is designed to demonstrate the TPS53355 in a typical, low-voltage application while providing a number of test points to evaluate the performance of the TPS53355.
