to set the output voltage at the desired values use the following design procedure:
1.
Equation 6
and choose a value Vin
output voltage range below Vox (it will equal Vox if one chooses Vin
2.
Equation 7
and check that at minimum mains voltage Vin
0.65V.
3.
Equation 8
4.
Equation 9
Determine the input RMS voltage Vin
Determine the divider ratio of the MULT pin (pin 3) bias:
