  • Patent number: 11474789
    Abstract: A power supplier circuit supplies a power signal to a codec of an audio apparatus. The power supplier circuit includes a random sequence generation circuit, a control circuit, and a power circuit. The random sequence generation circuit generates a random sequence. The control circuit outputs a first control signal according to the random sequence, a first reference signal, and the power signal. The power circuit generates the power signal according to the first control signal, such that the power signal is spread in response to the random sequence.

  • Patent number: 11387823
    Abstract: A PFM control circuit includes a switching circuit, a slope-decision circuit, a flip-flop, a first and a second comparison circuits. The first comparison circuit outputs a first signal according to an output voltage of a power conversion circuit. The switching circuit outputs a switching signal according to an output current of the power conversion circuit. The slope-decision circuit outputs a slope modulation voltage, and determines a slope modulation voltage with a first or a second slope according to the switching signal. The second comparison circuit outputs the second signal according to the slope modulation voltage. The flip-flop outputs a control signal to the power conversion circuit according to the first and the second signals. When the slope modulation voltage has the first or the second slope, the control signal has a first or a second frequency accordingly. The first frequency is higher than the second frequency.

  • Patent number: 11336106
    Abstract: A charging system includes: an input voltage supply circuit; a control circuit coupled to the input voltage supply circuit, configured to control the input voltage supply circuit to generate an input voltage according to a battery voltage of a target battery; and a charging circuit, coupled to the control circuit, configured to receive the input voltage and to provide a charging current to charge the target battery. The input voltage is generated according to a function that takes the battery voltage as a parameter. The input voltage is positively correlated with the battery voltage, and is greater than the battery voltage.
