For BUCK1, the voltage can be set using external feedback resistor. For all other bucks, the voltage is set by the default OTP settings and no resistor divider is required. For BUCK1, The internal voltage reference is set to 0.4 V.The output voltage is set with a resistor divider from the output node to the FB pin. TI recommends using a 1% tolerance or better to get accurate number. Use Equation 3 to calculate the value of R2.
To set the output voltage to 5 V, use a value of 294 kΩ for R1 and 25.5 kΩ for R2.
