I have questions about LTM4675/77:
If Rconfig is different values in table 2, table 3 (datasheet), how it work? Example: with LTM4675, Vout1_cfg is 10k, Vtrim1_cfg is 1.02k.
The formula for Vout is strictly linear in nature and includes Vref (0.5V) and the external resistor. When table 3 states 10.7k to achieve 2.5V and a 9.09k ends up at 2.3V you will see that LTM4675 will produce with 10k a voltage between 2.4 and 2.5V at respective Vout. Fine tuning is possible to end up at 2.5V if desired. But I do not see the point in not using the given values from the table? All given resistors are standard values from the 1% tolerance list.
Only the output voltage listed on the table from datasheet can be configured.
Unlike the analog solution, the resistor divider idea that can set the output voltage linearly.
The output voltage are saved as discrete values and the corresponding Rconfig/Rtrim points to these values respectively.
