  • Patent number: 11955879
    Abstract: In described examples, a controller includes a converter. The converter generates a first signal responsive to an input signal. A summing block is coupled to the converter. The summing block receives the first signal and generates a second signal. A limiter is coupled to the summing block and generates a third signal responsive to the second signal and a code signal. A logic block generates a target signal responsive to the third signal. The third signal transitions to an intermediate level at a first slew rate and the third signal transitions from the intermediate level to the target signal at a second slew rate.

  • Publication number: 20240039402
    Abstract: In some examples, a circuit includes a state machine. The state machine is configured to operate in a first state in which the state machine gates a pulse width modulation (PWM) signal provided for control of a power converter according to a first signal provided by a voltage control loop. The state machine is configured to operate in a second state in which the state machine gates the PWM signal according to a second signal provided by a current limit comparator. The state machine is configured to transition from the first state to the second state responsive to the second signal being asserted after the first signal is asserted in a switching cycle of the power converter. The state machine is configured to transition from the current state to the first state responsive to the first signal being asserted after the second signal in a switching cycle of the power converter.

  • Patent number: 8942333
    Abstract: Apparatuses and methods for phase aligning at least two clocks used by respective first and second circuitry systems, such as a memory controller and a DDR PHY interface in a system on a chip system. A first circuit samples a phase of a first clock used by the first circuitry system, and then a delay circuit selectively delays a second clock used by the second circuitry system and sets a delayed timing of the second clock. To economize resources and reduce chip area, a logic circuit receives the sampled phase of the first clock, determines which delayed timing matches timing of the sampled phase, and sets the delay circuit to a fixed delayed timing corresponding to the delayed timing that matches the sampled phase. Thus, phase alignment of the two clocks is achieved with fewer resources.
