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 switching frequencies. The use of a highly integrated package design results in highly reliable products with power densitiesof 79W/in3 (4.8W/cm3) for DIP-14, and 106W/in3 (6.5W/cm3) for SO-28. This combination of features and small size makes the DCP02 suitable for a wide range of applications.

ELECTROSTATIC DISCHARGE SENSITIVITY
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.
