The TPS40195EVM evaluation module (EVM) is a synchronous buck converter providing a fixed 3.3-V output at up to 20 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 TPS40195 4.5-V to 20-V Input, Voltage-Mode, Synchrns Buck Controller w/ PGOOD data sheet.

The TPS40195EVM is designed to use a regulated 12-V bus (8 V to 20 V) to produce a regulated 3.3-V output at up to 20 A of load current. TPS40195EVM is designed to demonstrate the TPS40195 in a typical 12-V bus to low-voltage application while providing a number of test points to evaluate the performance of the TPS40195 in a given application.
