  • Patent number: 9998004
    Abstract: A method and apparatus for regulating a non-isolated high voltage converter applies a PWM signal to a power transistor that couples an input voltage to a floating ground node to charge an inductor and generate an output voltage which is measured with a first floating comparator to disable the PWM signal upon detecting a high threshold output voltage, the first floating comparator having inputs connected across first and second resistive elements to measure a voltage across a feedback resistor connected in series with a diode between the output voltage and a neutral ground reference. Subsequently, the output voltage is measured with a second floating comparator to enable the PWM signal upon detecting a low threshold output voltage, where the second floating comparator has inputs connected across the first and second resistive elements to measure the feedback voltage across the feedback resistor.

  • Patent number: 9997992
    Abstract: A DC-DC power converter converts a DC input voltage at an input node into a DC output voltage at an output node. The converter has a main control loop that generates control signals used to control series-connected p-type and n-type switches that selectively connect an inductor to the input node or to ground while operating the converter in either a continuous-conduction mode (CCM) or a discontinuous-conduction mode (DCM). Zero-crossing detection (ZCD) circuitry detects when the inductor current reaches zero and generates a ZCD control signal used to control the n-type switch to inhibit negative inductor currents during the DCM mode. Overshoot-protection (OP) circuitry detects when the DC output voltage gets too high and generates an OP control signal used to control the n-type switch to inhibit overshoot conditions at the output node that can result from CCM-to-DCM mode transitions and from sudden reductions in output current loading.

  • Patent number: 9996458
    Abstract: A non-volatile memory is arranged to have a plurality of sectors. Each sector of the plurality of sectors includes a plurality of record locations. A memory controller includes an erase counter, a failed sector flag, and a retired sector flag for each of the plurality of sectors. If a record location of a sector fails to program, another location in the sector is selected to be programmed. The failed sector flag is set if a predetermined number of selected record locations of the sector fails to program. If the failed sector flag is set for a particular sector twice, and an erase count is greater than a predetermined erase count, then the retired sector flag is set for the failed sector indicating the sector is to be permanently retired from use. A new sector of the plurality of sectors becomes the current active sector for record programming operations. The method for retiring a sector occurs dynamically, during operation of the non-volatile memory.
