The TPS40190EVM-001 evaluation module (EVM) is a synchronous buck converter providing a fixed 1.5-V output at up to 10 A from a 12-V input bus. The EVM is designed to start up from a single supply, so no additional bias voltage is required for start-up. The module uses the TPS40190 reduced pin count synchronous buck controller.

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. The EVM can be modified to support output voltages from 0.9 V to 3.3 V by changing a single set resistor.
