3 Description

The DCR01 family is a series of high-efficiency, input-isolated, output-regulated DC/DC converters. In addition to 1-W nominal, galvanically-isolated output power capability, this range of DC/DC converters offer very low output noise, thermal protection, and high accuracy.

This combination of features and small size makes the DCR01 series of devices suitable for a wide range of applications, and is an easy-to-use solution in applications requiring signal path isolation.

CAUTION: This product has operational isolation and is intended for signal isolation only. It must not be used as a part of a safety isolation circuit requiring reinforced isolation. See definitions in the feature description.
