8.2.2.1.1 Boost Converter
The output voltage of the TPS65130/1 boost converter stage can be adjusted with an external resistor divider connected to the FBP pin. The typical value of the voltage at the FBP pin is the reference voltage, which is 1.213 V. The maximum recommended output voltage at the boost converter is 15 V. To achieve appropriate accuracy, the current through the feedback divider should be about 100 times greater than the current into the FBP pin. Typical current into the FBP pin is 0.05 μA, and the voltage across R2 is 1.213 V. Based on those values, the recommended value for R2 should be lower than 200 kΩ to set the divider current at 5 μA to 10 μA.
Calculate the value of resistor R1, as a function of the needed output voltage (VPOS), with Equation 1:
In this example, with R2 = 130 kΩ, choose R1 = 1 MΩ to set VPOS = 10.5 V.
