1 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.
