1. A direct current to direct current converter that controls an output voltage based on an error signal between a feedback voltage and a target voltage, comprising:
a temperature sensor;
a reference voltage generator circuit that generates a reference voltage;
a compensation calculator that calculates a compensation value from a temperature detected from the temperature sensor using a function of temperature;
a compensator that corrects a target initial value by the compensation value to generate a target value; and
a digital-to-analog converter that converts the target value to the target voltage based on the reference voltage.
