protection, the DCP01B 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 a power density of 40W/in
3
(2.4W/cm
3
). This combination of features and small sizes
makes the DCP01B suitable for a wide range of
applications.

SBVS012B − DECEMBER 2000 − REVISED OCTOBER 2004
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.
