DESCRIPTION
The DCP0124 family is a series of high efficiency,
24V input isolated DC/DC converters. In addition to
1W nominal galvanically isolated output power capability, 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 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.
