DESCRIPTION

The DCR01 family is a series of high-efficiency, input-

isolated, output-regulated DC/DC converters. In addition to

1W nominal, galvanically-isolated output power capability,

this range of DC/DCs offer very low output noise, thermal

protection, and high accuracy.

The DCR01 family is implemented in standard molded IC

packaging, giving standard JEDEC outlines suitable for

high-volume assembly.

The DCR01 is manufactured using the same technology

as standard IC packages, thereby achieving very high reli-

ability.
