Description
The PWR784EVM is designed as a single output DC-DC converter that demonstrates the TPS549D22 in
a typical low-voltage application while providing a number of test points to evaluate the performance. It
uses a nominal 12-V input bus to produce a regulated 1-V output at up to 40-A load current.
