1.1 Introduction

The LMG3650EVM-113 operates as a half-bridge daughter card that can be either part of a larger custom designed system or paired with a TI GaN mother board. TI provides two mother boards (LMG342X-BB-EVM and PFC23338EVM-107) to interface with LMG3650EVM-113. LMG342X-BB-EVM is a DC/DC buck-boost converter and can support up to 4kW. PFC23338EVM-107 is an AC/DC totem-pole PFC that can support up to 3.6kW. The LMG342X-BB-EVM is designed to operate LMG3650R025 in an open-loop synchronous buck or boost converter. Probe locations are provided to measure the logic and power stage voltages. PFC23338EVM-107 is designed to operate LMG3650R025in a closed loop totem-pole PFC.
