Introduction

The UCC12050DVE is a high efficiency, low-emissions, 5 kVrms Isolated DC/DC Converter Module capable of delivering up to 500 mW of power to isolated applications. Since the UCC12050DVE provides isolated power in an integrated package, this allows systems to reduce cost and size by removing the need for separate isolated power supplies. The UCC12050DVE delivers class-leading efficiency in power conversion from the primary to the secondary side while removing the need for bulky external transformer or power modules common in current designs. This integration allows for a much smaller area as well as a much shorter profile when compared to industry standards for power isolation techniques used in the field today. The UCC12050DVE is the default IC used in this EVM but any of the versions listed in Table 1-1 can be used for evaluation. Each of the component versions listed in Table 1-1 are pin-to-pin compatible, functionally equivalent, drop in replacements with respect to one another.
