PROBLEM TO BE SOLVED: To improve the performance of a converter circuit to achieve a longer life of the converter circuit.SOLUTION: A converter circuit includes a converter and a controller. The converter converts an input voltage to an output voltage. The controller receives a reference voltage, generates a slew voltage having a substantially constant first slew rate if the reference voltage changes from a first level to a second level, and controls the converter based on the slew voltage to cause the output voltage to change from a third level to a fourth level at a substantially constant second slew rate.
