摘要
A control circuit of digital control power supply circuit includes: first filter generating detection voltage having voltage level based on time average of output voltage of the digital control power supply circuit; A/D converter sampling feedback voltage having voltage level based on the output voltage at peak or bottom of the output voltage and converting the sampled feedback voltage into digital feedback data, and converting the detection voltage into digital detection data; error detector generating error data indicating difference between the feedback data and target data indicating target value of the feedback voltage; compensator generating duty command value adjusted to make the error data approximate zero; digital pulse modulator receiving the duty command value and generating pulse signal having duty ratio corresponding to the duty command value; and correction unit correcting the target data based on difference between the detection data and the feedback data.
