1.1 Introduction

This user’s guide provides directions for use of the UCC33420EVM-080 to evaluate the UCC33420-Q1 high frequency integrated transformer DC-DC converter, low emissions, 3kVRMS module from Texas Instruments. UCC33420-Q1 comes in a minimum footprint VSON-12 package which provides high-power density, 1.5W nominal power. The UCC33420-Q1 delivers class-leading efficiency in power conversion from the primary to the secondary side while removing the need for external transformers or power modules commonly required in existing designs. This integration allows for minimal printed circuit board (PCB) area as well as decreased height profile.
