Need to make sure I understand how to calculate the output voltage regulation tolerance, or range. Datasheet states Vout = 0.6V * (1 + R1/R2). So tolerances of R1 and R2 are obvious, but am I correct in assuming 0.6V here is the internal voltage reference? Datasheet has a parameter called Vregulated, with a min/max range of 0.591/0.609V. Is this the value range to be used for the 0.6V number in the output voltage equation?
The application generates 1V nominally. There is another datasheet parameter called Vloadreg. For the "I" version of the LTC3731, and at 1V, the datasheet implies 0.1% nom, and 0.% max. Is this in addition to the Vout equation? Also confused why the value is positive for voltages programmed below 1.2V, and negative for voltages programmed above 1.2V. Am I reading this correctly? (Glad it wasn't programmed for 1.2V, wouldn't know which to use...)
Bottom line: Don't know how to calculate a worst case voltage regulation range over temperature for this part based on this datasheet. Any other datasheet parameters that would impact the regulated output voltage range?
