7. Setting output voltage
This IC is operated that output voltage is REF≒V
And it is operated that output voltage is feed back to FB pin in case the output voltage is 0.7V to 2.0V.
It is operated that the resistance division value of the output voltage is feed back to V
more than 2.0V.
And then the frequency is also in proportion to the divided ratio.
