User's Guide

Using the UCC14240EVM-052 for Biasing Traction Inverter Gate Driver ICs Requiring Single, Positive or Dual, Positive/Negative Bias Power

Abstract

This user’s guide provides a description as well as directions for use of the UCC14240EVM-052 to evaluate the UCC1424x-Q1 or UCC1524x-Q1, high frequency, integrated transformer, DC-DC converter modules from Texas Instruments. The EVM comes with UCC14240-Q1 populated by default but can accommodate any of the pin-to-pin compatible, alternate versions listed in Table 1-1. All performance data and waveforms shown within this document were obtained testing the UCC14240-Q1. This EVM allows designers to quickly and efficiently evaluate the UCC14240-Q1 for use in automotive or industrial applications requiring gate driver IC bias power as high as 2-W, meeting up to 3-kVRMS isolation.

1 Introduction

The UCC14240-Q1 is a high efficiency, low-emissions, 3 kVRMS Isolated DC-DC Converter capable of delivering up to 2-W of power. Since the UCC14240-Q1 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 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 minimal printed circuit board (PCB) area as well as decreased height profile.
