1.1 Introduction

The TPS544B28RBHEVM evaluation module (EVM) is a buck converter built using the TPS544B28 in an RBH package. The EVM is designed to accommodate various settings through jumper options. The device allows programming and monitoring through the PMBus® interface, and therefore, the design is not optimized for any specific condition. The test data in this user's guide was all collected for 12V input voltage, 1V output voltage, and 800kHz switching frequency up to 20A output current, unless otherwise specified.
