Frequency control circuit, control method and switching converter
A frequency control circuit, applied in a switching converter, can be configured to: regulate an off time of a power transistor of the switching converter in one switching cycle according to an on time of the power transistor, or regulate the on time of the power transistor in one switching cycle according to the off time of the power transistor; and maintain an operating frequency of the switching converter to be within a predetermined range.
