Abstract:
A power converter control circuit includes a first ramp generator connected to an input voltage and configured to produce a first ramp signal; a second ramp generator connected to the input voltage and configured to produce a second ramp signal; an error amplifier configured to produce an error amplifier output. The first ramp signal and the error amplifier output are used to produce a first (pulse width modulation) PWM signal and the second ramp signal and the error amplifier output are used to produce a second PWM signal. The first and second PWM signals control an operating state of the circuit. In some embodiments, the first ramp signal includes an extended ramp reset time. In some embodiments, the first ramp generator includes a switching device, a current source, and a capacitor.
