Product Introduction

Overview

The DCR011205U/1K is a high-efficiency, input-isolated, output-regulated DC/DC converter from Texas Instruments. It belongs to the DCR01 family, which offers 1-W nominal, galvanically-isolated output power capability. These converters are known for their very low output noise, thermal protection, and high accuracy. The small size and comprehensive feature set make the DCR01 series suitable for a wide range of applications, particularly those requiring signal path isolation.
