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.
