摘要： A power supply system and method includes a switch state controller that is operational to control a switching power converter during certain power loss conditions that cause conventional switch state controllers to have diminished or no functionality. In at least one embodiment, during certain power loss conditions, such as when an auxiliary power supply is in standby mode or when the switching power converter is not operating, a power supply for the switch state controller does not provide sufficient operating power to the switch state controller during certain power loss conditions. In at least one embodiment, during such power loss conditions power is generated for the switch state controller using sense input and/or sense output currents of the switching power converter to allow an integrated circuit (IC) switch state controller to generate a control signal to control a switch of the switching power converter.

摘要： A power control system and method senses input and/or output voltages of a power supply using sense currents in order for an integrated circuit (IC) switch state controller to generate a control signal to control a switch of the power control system. By sensing sense currents, the power control system can eliminate at least one sense resistor used in a voltage sense system. The sense current(s) can be used to provide power and sensing to the switch state controller. In at least one embodiment, the sense current(s) provide power to the switch state controller when auxiliary IC power is unavailable or diminished, such as during start-up of the IC. In at least one embodiment, the IC draws more sense current from an input of the power control system than the output of the power control system to, for example, minimize impact on the output voltage of the power supply.

摘要： A delta-sigma analog to digital converter (ADC) having an intermittent power down state between conversion cycles provides for power consumption savings when the converter is in a lower sample rate operating mode. Clocks provided to the digital portions of the converter are disabled, except for a periodic interval in which a conversion is performed at the higher selectable sample rate of the converter. The analog portions of the converter can also be disabled, but are re-enabled for a predetermined time period and reset before the digital clocks are enabled, so that the loop filter and feedback value supplied from the quantizer to the loop filter are stable prior to each conversion.

In at least one embodiment, the delta sigma modulator includes two ranges of available output values and a range of one or more unavailable intermediate output values, wherein the range of one or more unavailable intermediate output values represent a gap in available output values. Each unavailable intermediate output value represents an output value that is not generated by the delta sigma modulator. In at least one embodiment, the delta sigma modulator includes a quantizer output remapping module that remaps quantizer output values within the range of one or more unavailable intermediate output values of the delta sigma modulator to new output values within one of the ranges of available output values.

摘要： A system-on-chip (SoC) integrated circuit including an interleaved delta-sigma analog to digital converter (ADC) provides for reduced noise in the ADC conversions. The ADC is operated intermittently and the balance of the digital circuits forming the system are halted while the conversions take place. The halted portion of the system may include an output low-pass filter of the ADC. The system may include a processor core or other logic having a clock frequency unrelated to the ADC modulator clock frequency that is not otherwise clock-managed to reduce noise induced in the converter output by the operation of the core or other logic.

摘要： A power control system includes a current sense resistor located on an output side of a switching power converter. By locating the current sense resistor on the output side of the switching power converter, the current sense resistor conducts a sense current when a control switch of the switching power converter is nonconductive. Since a duty cycle of the control switch is larger for a low input voltage than for a higher input voltage, the current sense resistor conducts current for a shorter time duration for low input voltages than for higher input voltages. Thus, the root mean square (RMS) of a sense current in the current sense resistor and, thus, power dissipation by the current sense resistor, is lower during low input voltages than power dissipation in conventionally located current sense resistors. The RMS of the sense current is approximately constant across a full range of input voltages.
