HIGH EFFICIENCY
DESCRIPTION
DCR01 family is a series of high-efficiency, input-
isolated, output-regulated DC/DC converters. In addi-
tion to 1W nominal, galvanically-isolated output power
capability, this range of DC/DCs offer very low out-
put noise, thermal protection and high accuracy.
The DCR01 family is implemented in standard molded
IC packaging, giving standard JEDEC outlines suit-
able for high-volume assembly.
The DCR01 is manufactured using the same technol-
ogy as standard IC packages, thereby achieving very
high reliability.
NOTE: (1) SO version available Q3 2000.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
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 degrada-
tion 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.
