Abstract
A switch frequency control apparatus comprises a timer coupled between a bias voltage and ground, wherein the timer comprises a first input configured to receive a ramp, a second input configured to receive a threshold voltage and an output configured to be connected to an input of a PWM circuit, wherein the output of the timer is used for setting either a constant on-time or a constant off-time of a power converter and a threshold generator coupled between the bias voltage and ground, wherein the threshold generator is configured to receive a plurality of control signals of the power converter and generate the threshold voltage based upon a duty cycle of the power converter.
