1.1 Introduction

The LMG2650EVM-100 operates as a half-bridge daughtercard that can be either part of a larger custom designed system or paired with the mother board. TI provides a mother board (LMG342X-BB-EVM) to interface with LMG2650EVM-100. LMG342X-BB-EVM can support up to 4kW. The mother board is designed to operate LMG2650 in an open-loop synchronous buck or boost converters. Probe locations are provided to measure the logic and power stage voltages. This board assembly is not a good choice for Double Pulse Testing (DPT).

The LMG2650EVM-100 is designed for use in AC/DC, DC/DC and DC/AC applications.
