DESCRIPTION
The DCP01B series is a family of 1W, unregulated,
isolated DC/DC converters. Requiring a minimum of
external components and including on-chip device
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/in3 (2.4W/cm3). This combination of features
and small size makes the DCP01B suitable for a wide
range of applications.

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.
