摘要： In one embodiment, the digital pulse width modulator of these teachings includes comparators and a number of phases and capable of increasing resolution without increasing clock frequency. In another embodiment, the digital pulse width modulator (DPWM) of these teachings includes equality comparators and a number of phases and increases resolution without increasing clock frequency. A further embodiment of the system of these teachings includes a priority encoded comparator component (in one instance including a number of comparators) comparing duty cycle commands against preset minimums, that embodiment being referred to as a frequency Foldback component. Other embodiments and embodiments of the method of these teachings are also disclosed.

摘要： A method and apparatus for converting a DC voltage to a lower DC voltage, provides for conducting current from an input terminal, through an inductor to charge a capacitor connected to the inductor at an output terminal and to provide a varying range of load current from the output terminal, alternately switching the input terminal between a supply voltage and a ground potential to produce a desired voltage at the output terminal that is lower than the supply voltage, while providing the varying range of load current, and disconnecting the input terminal from both the supply voltage and the ground potential to reduce an increase in voltage at the output terminal caused by a substantial reduction in the load current, while current through the inductor adjusts in response to the reduced load current.

摘要： An inductor current estimator for a switching power supply includes a first sensing and averaging component that generates an average of a switch voltage and a second sensing and averaging component that generates an average of an output voltage of the switching power supply. A first subtraction component receives the average of the switch voltage and the average of the output voltage. A first multiplying component receives an output of the first subtraction component and multiplies the output of the first subtraction component by a first model parameter. A second multiplying component multiplies an input to the second multiplying component by a second model parameter. An adding component adds an output of the first multiplying component and an output of the second multiplying component. A delay component receives an output of the adding component and provides an output to an input of the second multiplying component.
