DCP02 Series
SBVS011C MARCH 2000 REVISED DECEMBER 2005
Miniature, 2W, Isolated
UNREGULATED DC/DC CONVERTERS
Up To 89% Efficiency
The DCP02 series is a family of 2W, isolated,
unregulated DC/DC converters. Requiring a minimum
Thermal Protection
of external components and including on-chip device
Device-to-Device Synchronization
protection, the DCP02 series provides extra features
SO-28 Power Density of 106W/in
3
(6.5W/cm
3
)
such as output disable and synchronization of
EN55022 Class B EMC Performance
switching frequencies.
UL1950 Recognized Component
The use of a highly integrated package design results
in highly reliable products with power densities of
JEDEC 14-Pin and SO-28 Packages
79W/in
3
(4.8W/cm
3
)
for
DIP-14,
and
106W/in
3
(6.5W/cm
3
) for SO-28. This combination of features
and small size makes the DCP02 suitable for a wide
Point-of-Use Power Conversion
range of applications.

ABSOLUTE MAXIMUM RATINGS
DCP02 Series
SBVS011C MARCH 2000 REVISED DECEMBER 2005
This integrated circuit can be damaged by ESD. Texas Instruments 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.
For the most current package and ordering information, see the Package Option Addendum at the end of this
data sheet, or see the TI website at www.ti.com.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
