  • Patent number: 10784780
    Abstract: A controller circuit for generating a Pulse-Width Modulation (PWM) signal for activating a switching device of a Switched-Mode Power Supply (SMPS) includes gap detection circuitry, Pulse Frequency Modulated (PFM) circuitry, PWM circuitry and logic circuitry. The gap detection circuitry is configured to generate a shift signal based on an indication of a voltage difference between a reference voltage and a feedback voltage corresponding to voltage output by the SMPS. The PFM circuitry is configured to generate a hold signal indicating a target PFM frequency for the PWM signal. The PWM circuitry is configured to shift, based on the shift signal, a pedestal current to generate a shifted pedestal current and to generate, based on the shifted pedestal current, a peak signal indicating a target PWM on time for the PWM signal.

  • Patent number: 9490719
    Abstract: According to an embodiment, a power supply controller includes a first controller, a second controller, a transformation circuit, a switch signal generator. The first controller is configured to provide a first control parameter based on a first power supply measurement signal and the second controller is configured to provide a second control parameter based on a second power supply measurement signal. The transformation circuit is configured to provide a first switching control parameter dependent on both the first control parameter and the second control parameter, and to provide a second switching control parameter dependent on both the first control parameter and the second control parameter. The switch signal generator is configured to generate switching signals that depend on both the first switching control parameter and the second switching control parameter.
