I'm trying to use a STOD1317BTPUR DC-DC Boost converter to drive a 12v OLED Display from a 1-cell lipo (~ 3v - 4.5v). The thing is that in the application circuit provided in the datasheet the values for the resistors R1 and R2 are not detailed, neither a formula to obtain them. I've looked for different application circuits from other parts but what confuses me about this one is Vout and Vo_set. I don't understand the difference between them. (I know it has something to do with the LDO it has on the output, but I don't know if this changes something in the formula of the voltage divider).
Leave it to ST to publish a crap datasheet...
You can use that feedback voltage and your desired output voltage to calculate the voltage divider values.
*OTA usually stands for operation transconductance amplifier. If that is what it actually is, then this answer is wrong. If I was designing with this part, I would reverse engineer an eval board circuit to confirm this hypothesis.
