User's Guide

Using the UCC14341EVM-069 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 UCC14341EVM-069 to evaluate the UCC14341-Q1, high frequency, integrated transformer, DC-DC converter module from Texas Instruments. The EVM comes with UCC14341-Q1 populated by default but can also accommodate UCC14340-Q1. UCC14341-Q1 and UCC14340-Q1 are pin-to-pin compatible and functionally equivalent. All performance data and waveforms shown within this document were obtained testing the UCC14341-Q1. This EVM allows designers to quickly and efficiently evaluate the UCC14341-Q1 for use in automotive or industrial applications requiring gate driver IC bias power as high as 1.5 W, meeting up to 5-kVRMS isolation.

The user's guide can accompany UCC14341EVM-069, HVP069, Rev E1 and Rev A. Rev E1 and Rev A are identical.

1 Introduction

The UCC14341-Q1 is a high efficiency, low-emissions, 5 kVRMS Isolated DC-DC Converter capable of delivering 1.5-W of power. Since the UCC14341-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 UCC14341-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.
