For example, for a given output-power rating, such a power-supply module may be smaller, more efficient, and more reliable than, and may run cooler than, a power-supply module having the inductor mounted outside of the package or side-by-side with other components. And for a given size, such a module may have a higher output-power rating than a module having the inductor mounted outside of the package or side-by-side with other components.

摘要： A controller for a switch mode regulator with discontinuous conduction mode (DCM) correction which includes a correction network and a modulator. The correction network detects a low load condition indicative of regulation error during DCM and asserts an adjust value indicative thereof. The modulator receives the adjust value and adjusts operation accordingly to improve regulation during DCM. The correction network receives or determines a regulation metric, such as periods between successive pulses of a pulse control signal, or a current sense signal indicative of load current, and compares the regulation metric with one or more thresholds for determining the level of adjustment. Adjustment may be made using one or more methods, such as adjusting pulse on-time, adjusting pulse off-time, adjusting frequency of operation, etc.

摘要： A two-channel time-interleaved analog-to-digital converter (TIADC) system that provides for estimation and correction of offset, gain, and sample-time errors. Error in the offsets of the two ADCs that form the TIADC produces a spurious signal at the Nyquist frequency that can be used to minimize the difference of offsets of the ADCs. The difference in gain between the two ADCs produces spurious signals reflected around the Nyquist frequency whose magnitudes can be reduced by minimizing the difference in signal power between the two ADCs. An Automatic Gain Control loop corrects the scaling of the input signal due to the average of the gains of the ADCs. Phase error produces spurious signals reflected around the Nyquist frequency that are π/2 out of phase with those due to the gain error. Minimizing the difference between the correlation of consecutive signals from the ADCs reduces the magnitude of these image tones.

摘要： Signals propagating from an aggressor communication channel can cause detrimental interference in a victim communication channel. One or more noise cancellers can generate an interference compensation signal to suppress or cancel the interference based on one or more settings. A controller can execute algorithms to find preferred settings for the noise canceller(s). The controller can use a feedback signal (e.g., receive signal quality indicator) received from a victim receiver during the execution of the algorithm(s) to find the preferred settings. One exemplary algorithm includes sequentially evaluating the feedback resulting from a predetermined list of settings. Another algorithm includes determining whether to move from one setting to the next based on the feedback values for both settings. Yet another algorithm includes evaluating a number of sample settings to determine which of the sample settings result in a better feedback value and searching around that sample setting for a preferred setting.

摘要： A DC-DC voltage converter has a pair of switching transistors to provide an output voltage and are alternately switched in a boost mode of operation responsive to control signals. An inductor is connected to the pair of switching transistor and has an inductor current flowing there through. A current sensor monitors an input current and generates a current sense signal responsive thereto. Control circuitry generates the control signals to the second pair of switching transistors responsive to the current sense signal, the output voltage and a current limit signal, wherein when the current limit signal indicates the inductor current exceeds a current limit the control signals configure the pair of switching transistors to decrease the inductor current.

摘要： A method and system control the adding or dropping of phases in a multiphase voltage regulator. The regulator has an efficiency and this efficiency of the regulator is calculated for a given number of phases being activated from an output voltage, input voltage, output current, and duty cycle of the regulator. The efficiency of the regulator is also calculated if a phase is added using the derivative of the duty cycle as a function of the output current. The efficiency of the regulator is further calculated if a phase is dropped using the derivative of the duty cycle as a function of the output current. From these operations of calculating, a phase is either added, dropped, or the phase is maintained at its current value to thereby optimize the efficiency of the regulator.

摘要： A DC/DC converter has an output voltage and sources an output current to a load. The DC/DC converter includes an error amplifier with a reference input and a summing input. The reference input is electrically connected to a reference voltage. The summing input is electrically connected to the output voltage and the output current. The summing input is configured for adding together the output voltage and the output current. The error amplifier issues an error signal and adjusts the error signal dependent at least in part upon the output voltage and the output current. A comparator receives the error signal. The comparator has a ramp input electrically connected to a voltage ramp signal. The comparator issues an output signal that is based at least in part upon said error input. A power switch has an on condition and an off condition, and supplies dc current to the load when in the on condition. The power switch has a control input electrically connected to the comparator output signal. The power switch is responsive to the control input to change between the on condition and the off condition to thereby adjust the output current of the DC/DC converter.
