4. No-load operation
The following condition should be meet to prevent from
overvoltage and audible noise during no-load or light-load
operation.

, dead time of AC input current will
extend.
5. How to prevent from intermittent switching of low
frequency
An intermittent switching, which frequency is lower than 10Hz,
occurs in some applications.
In this case, it is possible to prevent from this intermittent
switching to reduce feedback gain by decreasing the
resistance of R4. (See Fig. 2)
You must check the effect thoroughly because this intermittent
switching depends on load, temperature and input condition.
