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.
