Page 2: Introduction
1.1 Description The TPS40190EVM-001 is designed to use a regulated 12-V (10 V–14 V) bus to produce a high current, regulated 1.5-V output at up to 10-A of load current. The TPS40190EVM-001 is design to demonstrate the TPS40190 in a typical regulated bus to low-voltage application while providing a number of test points to evaluate the performance of the TPS40190 in a given application. -
