7.3.11 Adjustable Output Voltage (FB, FB1, and FB2)
Using an external resistor divider selects an output voltage between 1.5 V and 20 V. Use Table 2 to calculate the output voltage (VO). The recommended value for both R1 and R2 is less than 100 kΩ.
Equation 1. 
where
- V(FB) = 1.233 V
Figure 21. TPS7B770x-Q1 Output Voltage Setting Connection The TPS7B770x-Q1 family of devices can also be used as a current-limited switch by connecting the FB pin to the GND pin.
