Abstract
A switch frequency control apparatus comprises a timer configured to receive a ramp and a threshold voltage, and generate a control signal for setting gate drive signals of a power converter, a ramp generator configured to generate the ramp through charging a ramp capacitor using a current source having a current level equal to a bias voltage divided by a resistor, and a threshold generator configured to generate the threshold voltage proportional to the bias voltage.
