The present application discloses a method and apparatus for determining resistance values of a dynamic voltage-adjusting circuit. The method includes: determining a reference voltage, a maximum output voltage value, and a minimum output voltage value of the dynamic voltage-adjusting circuit; determining, according to the reference voltage and the maximum output voltage value, a first relational expression between the reference voltage, the maximum output voltage value, and multiple resistors of the dynamic voltage-adjusting circuit, and determining, according to the reference voltage and the minimum output voltage value, a second relational expression between the reference voltage, the minimum output voltage value, and the multiple resistors; and determining a group of resistance values of the multiple resistors according to the first relational expression and the second relational expression. The group of resistance values determined thereby is a group of resistance values adapting to the reference voltage. By adjusting the resistance values of the multiple resistors to fit with the varying reference voltage, it is ensured that voltage values output by the dynamic voltage-adjusting circuit can fall within a same range when the reference voltage takes different values.
