摘要:A DC-DC converter control circuit, to control a DC-DC converter having aninductor and two switches, including a first feedback circuit; a second feedback circuit; asynthesis circuit to add a first feedback voltage indicating a DC component of an inductor
current based on an output voltage of the DC-DC converter and a second feedbackvoltage indicating an AC component thereof to generate a third feedback voltage; acomparator to compare the third feedback voltage with a reference voltage to output acomparison result; and an on-time adjusting circuit to adjust on/off time of the switchesbased on the comparison result for outputting a control signal depending on theadjusting result. The second feedback voltage is generated based on a differencebetween input and output voltages of the DC-DC converter when the control signal islow and based on the output voltage when the control signal is high.
