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–DCs 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.
