Description

The TPS40193EVM-001 evaluation module (EVM) is a synchronous buck converter that provides a fixed 1.8 V output at up to 10 A from a 12 V input bus. The EVM is designed to power up from a single supply, so no additional bias voltage is required for start-up.

The demonstration module uses the TPS40193 reduced pin count mid-voltage synchronous buck controller. The TPS40193EVM-001 is designed to use a regulated 12 V (8 V - 14 V) bus to produce a regulated 1.8 V output at up to 10 A of load current. The EVM is designed to demonstrate the capabilities of the TPS40193 in a typical 12 V bus to low-voltage application while providing a number of test points for evaluating the TPS40193 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.
