Introduction
The TPS40075EVM-001 evaluation module (EVM) is a synchronous buck converter providing a fixed
1.5-V output at up to 15 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 TPS40075 High Frequency
Controller with remote sense. The module uses the TPS40075 High Frequency Synchronous BUCK
Controller with Remote Sense and Enable.

TPS40075EVM-001 is designed to use a regulated 12-V bus (between 10 V and 14 V) to produce a high
current, regulated 1.5-V output at up to 15 A of load current. The TPS40075EVM-001 is design to
demonstrate the TPS40075 in a typical regulated bus to low-voltage application while providing a number
of test points to evaluate the performance of the TPS40075 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 resistor. The
TPS40075EVM-001 has been built to the sample application used in the TPS40075 Datasheet except the
switching frequency has been lowered to 400 kHz to reduce switching losses in the Power FETs, and the
