DESCRIPTION
DCR01 family is a series of high-efficiency, inputisolated, 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 reliability.
NOTE: (1) SO version available Q3 2000.

ELECTROSTATIC
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 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.
The information provided herein is believed to be reliable; however, BURR-BROWN assumes no responsibility for inaccuracies or omissions. BURR-BROWN assumes
no responsibility for the use of this information, and all use of such information shall be entirely at the user’s own risk. Prices and specifications are subject to change
without notice. No patent rights or licenses to any of the circuits described herein are implied or granted to any third party. BURR-BROWN does not authorize or warrant
any BURR-BROWN product for use in life support devices and/or systems.
