6. Setting standard voltage (REF)
7. Setting output voltage
REF
This IC is operated that output voltage is REF×2≒FB.
And it is operated that output voltage is feed back to FB pin.

It is available to set the reference voltage (REF)
with outside supply voltage ×2 [V] by using outside
power supply voltage.
It is available to set the reference voltage (REF) by
the resistance division value from REG2 in case
REF is not set from an external power supply.
