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.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
