  • Patent number: 12278648
    Abstract: A device including an input to receive a clock signal, a ramp start program register, a ramp start active register, a ramp stop program register, a ramp stop active register, a ramp slope program register, a ramp slope active register, an update controller, the update controller to update, based on a programmable condition, respectively, the ramp start active register contents, the ramp stop active register contents and the ramp slope active register contents, and a ramp controller to generate a ramp signal, the ramp signal to begin at the value reflective of the ramp start active register contents, the ramp signal to change value at each cycle of the clock signal based on the value reflective of the ramp slope active register contents, and the ramp signal to stop at the value reflective of the ramp stop active register contents.

  • Publication number: 20240088893
    Abstract: A device includes a PWM circuit to generate a complementary PWM signal comprised of a positive polarity PWM signal and a negative polarity PWM signal. The positive polarity signal may drive a high-side switch. A trigger multiplexer may take as input the negative polarity PWM signal and may force an output based on a predetermined condition, the predetermined condition including but not limited to the maximum on-time of a low-side switch. The output of the trigger multiplexer may drive a low-side switch. The high-side switch and the low-side switch may drive a load.

  • Publication number: 20240006982
    Abstract: An inductor-inductor-capacitor (LLC) power converter includes a current input interface to receive a current input indication. The current input indication includes a voltage to represent a current passing through of a primary side of the LLC power converter. The LLC power converter includes voltage input interface to receive a voltage input. The voltage input is to include a representative voltage to be provided from a secondary side of the LLC power converter. The LLC power converter includes a control circuit to generate pulsed-width modulation (PWM) control signals for the LLC power converter. The control circuit is to match an on-time period of a first leg and a second leg of the LLC power converter and based upon the current input indication and the voltage input.
