Page 3: Introduction
Introduction www.ti.com Introduction The BSR054EVM evaluation module uses the TPS543C20EVM-054 device. The TPS543C20EVM-054 is a highly integrated synchronous buck converter that is designed for up to 40-A current output. Before You Begin The following warnings and cautions are noted for the safety of anyone using or working close to the TPS543C20EVM-054. -
Page 4: Description
The BSR054EVM is designed as a single output DC/DC converter that demonstrates the TPS543C20EVM-054 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 0.9-V output at up to 40-A load current. -
