9.2.2.1 Programming The Output Voltage
While the output voltage of the TPS63070 is adjustable, the TPS630701 is set to a fixed voltage. For fixed output versions, the FB pin must be connected to the output directly. The adjustable version can be programmed for output voltages from 2.5V to 9V by using a resistive divider from VOUT to GND. The voltage at the FB pin (VREF)is regulated to 800mV. The value of the output voltage is set by the selection of the resistive divider from Equation 6 . It is recommended to choose resistor values which allow a current of at least 2uA, meaning the value of R2 shouldn't exceed 400kΩ. Lower resistor values are recommended for highest accuracy and most robust design.

| 3.3 V | 470 kΩ | 150 kΩ |
| 5.0 V | 680 kΩ | 130 kΩ |
| 5.3 V | 560 kΩ | 100 kΩ |
| 5.5 V | 300 kΩ | 51 kΩ |
| 6.5 V | 360 kΩ | 51 kΩ |
| 9 V | 402 kΩ | 39 kΩ |
