DESCRIPTION
The DCP02 series is a family of 2W, unregulated,
isolated DC/DC converters. Requiring a minimum of
external components and including on-chip device
protection, the DCP02 series provides extra features
such as output disable and synchronization of switch-
ing frequencies.
The use of a highly integrated package design results
in highly reliable products with power densities of
79W/in3 (4.8W/cm3) for the 14-PDIP, and 106W/in3
(6.5W/cm3) for the SO-28(1). This combination of
features and small size makes the DCP02 suitable for
a wide range of applications.
NOTE: (1) SO-28 version available January, 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 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.
