ADVANCE INFORMATION for pre-production products; subject to change without notice.
The output voltage of the TPS6281x-Q1 is adjustable. It can be programmed for output voltages from 0.6 V to 5.5 V, using a resistor divider from VOUT to GND. The voltage at the FB pin is regulated to 600 mV. The value of the output voltage is set by the selection of the resistor divider from Equation 7. It is recommended to choose resistor values which allow a current of at least 2 µA, meaning the value of R2 should not exceed 400 kΩ. Lower resistor values are recommended for highest accuracy and most robust design.
