Introduction

The UCC14240-Q1 is a high efficiency, low-emissions, 3 kVRMS Isolated DC-DC Converter capable of delivering up to 1.5-W of power. Because the UCC14240-Q1 provides isolated power in an integrated package, systems can reduce cost and size by removing the need for separate isolated power supplies. The UCC14240-Q1 delivers class-leading efficiency in power conversion from the primary to the secondary side while removing the need for bulky external transformers or power modules commonly used in existing designs. This integration allows for a much smaller printed circuit board (PCB) area as well as a much lower height profile when compared to industry standards for power isolation techniques used in the field today.
