  • Page 2: Introduction

    1 Introduction The TPS51113-EVM evaluation module (EVM), is a high efficiency single phase synchronous buck converter providing a fixed 1.2-V output at up to 25 A from a 12-V input bus. The EVM uses the TPS51113 synchronous buck controller. 2 Description The TPS51113-EVM is designed to use a regulated 12-V (8 V to 14 V) bus to produce a high current, regulated 1.2-V output at up to 25 A of the load current.
