When checking the initial switcher operation with an
oscilloscope, there will be some concern of circuit instability
due to the apparent random switching of the output. The
oscilloscope will be difficult to synchronize. This is not a
problem. It is a normal operating characteristic of this type
of switching regulator and is caused by the asynchronous
operation of the comparator to that of the oscillator.
