  • Patent number: 10673337
    Abstract: A switch-node rising edge detection circuit is provided for a switched-mode DC/DC boost converter. A high-side gate-driver couples a gate of the high-side NMOS power transistor to either a first terminal of a bootstrap capacitor or the switch-node. The detection circuit includes an AND gate that receives an activation signal on a first input and provides a switching signal to the high-side gate-driver. A PMOS transistor is coupled in series with an inverter between the first terminal of the bootstrap capacitor and a second input of the AND gate. The inverter receives supply voltages from the first terminal of the bootstrap capacitor and the switch-node. The gate of the PMOS transistor receives the activation signal. An NMOS transistor is coupled between an output voltage and a node between the PMOS transistor and the inverter. A gate of the NMOS transistor is coupled to the bootstrap capacitor's first terminal.

  • Publication number: 20200064893
    Abstract: A power supply system can include at least one power switch to generate an output current based on an input voltage in response to a switching signal to generate an output voltage. A feedback system generates a feedback current based on the output voltage. A mode detector generates a control current associated with the output current based on the feedback current and selects between a pulse-width modulation (PWM) mode and a pulse mode based on an amplitude of the control current. The PWM mode is associated with a sequential on-time and off-time of the at least one power switch, and the pulse mode is associated with adding an idle time between the on-time and the off-time of the at least one power switch based on the switching signal. A gate driver system generates the switching signal based on the mode.

  • Patent number: 10482921
    Abstract: A memory system includes a memory device, a command clock (CK_t clock) that provides a first clock signal at a first frequency, and a data path clock (WCK_t clock) that provides a second clock signal at a second frequency different than the first frequency. Data path circuitry is synchronized with the WCK_t clock and provides an error detection code (EDC) hold pattern during an idle state. EDC hold pattern synchronization logic synchronizes a start of transmission of the EDC hold pattern synchronous to the CK_t clock.

  • Patent number: 10447298
    Abstract: An integrated circuit includes first and second double data rate (DDR) shift registers. A multiplexor outputs a serialized data burst by selecting between a first output stream of the first DDR shift register and a second output stream of the second DDR shift register based upon a received selector signal. The selector signal is derived from clock doubling circuitry that provides a frequency that is twice a frequency of a first clock driving the first DDR shift register.
