Abstract:
Constant on-time control circuit includes a comparing circuit including a comparator including a positive input end for receiving a control voltage; a negative input end for receiving a feedback voltage from the output voltage of the DC/DC converter; and an output end for outputting a comparing signal; and a voltage adjusting circuit coupled to the output end of the comparator for adjusting the control voltage; and a pulse generator coupled to the output end of the comparator for generating a pulse signal to control a switch set of the DC/DC converter according to the comparing signal.
