Abstract: The present invention provides a built-in ripple injection circuit and a control chip, in which a divided feedback voltage is obtained by division of an output voltage by a feedback circuit, and high-frequency ripple in the output voltage is obtained by an operational amplifier and a first capacitor. Moreover, the high-frequency ripple is injected at a third terminal of a source follower. As a result, the feedback voltage is a superimposition of the divided feedback voltage with the high-frequency ripple. This can enhance stability and interference resilience of a power supply system operating in a ripple-based COT control mode. Further, the built-in ripple circuit can be integrated in the control chip. This dispenses with the use of a large capacitor and satisfactorily addresses applications requiring on-chip integration of the feedback circuit, reducing the cost of the power supply system.
