DC/DC CONVERTER AND CONTROL METHOD THEREOF |
摘要 |
A DC/DC converter and a control method thereof are disclosed. The DC/DC converter comprises: an output voltage regulation circuit configured to regulate an output voltage of the DC/DC converter, so as to output a duty cycle regulation signal; a PWM generator electrically coupled to the output voltage regulation circuit and configured to generate a first duty cycle signal according to a first clock signal and the duty cycle regulation signal; a detection circuit configured to output a control signal according to a second clock signal and a feedback signal, wherein the feedback signal is configured to detect whether or not the transient change of an input voltage of the DC/DC converter occurs; and a CBC regulation circuit electrically coupled to the PWM generator and the detection circuit, and configured to receive the first duty cycle signal and the control signal and output a second duty cycle signal. |
