DESCRIPTION
The DCP0115 family is a series of high efficiency,
15V input isolated DC/DC converters. In addition to
1W nominal galvanically isolated output power capa-
bility, the range of DC/DCs are also fully
synchronizable. The devices feature thermal shutdown,
and overload protection is implemented via watchdog
circuitry. Advanced power-on reset techniques give
superior reset performance and the devices will start
into any capacitive load up to full power output.
The DCP01 family is implemented in standard-molded
IC packaging, giving outlines suitable for high volume
assembly.

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.
