摘要： An integrated circuit regulates current flowing from a battery to a load without requiring an external current sense resistor. The IC includes a primary charge pump; a model charge pump; a current sense circuit, a first control circuit to force a voltage level at the output of the model charge pump to be equal to a voltage level at the output of the primary charge pump; and, a second control circuit to force a model current put out by the model charge pump to be equal to a reference current. Current passing through the primary charge pump is regulated at a level established by the capacitance value of an external flying capacitor irrespective of input voltage variation of the battery power source.

摘要： A controller for switching power supplies includes a nonlinear controller component capable of providing a duty cycle to a pulse width modulator. The duty cycle corresponds to at least one predetermining switching power supply state variable. A nonlinear controller component receives as inputs at least one predetermined switching power supply state variable. A relationship between duty cycle and at least one predetermined switching power supply state variable is obtained by a predetermined method. The nonlinear controller component comprises memory for access by an application component. The memory includes a data structure stored in memory and a plurality of duty cycles. Each of the plurality of duty cycles has a corresponding at least one predetermined switching power supply state variable. Each duty cycle, when provided to the pulse width modulator of the switching power supply, provides a predetermined switching power supply output.

摘要： A digital controller includes a sampling component that samples an output signal from a system and an input signal to the system at a first sampling rate, which is at least equal to a predetermined operating rate. An input parameter obtaining component obtains a plurality of input parameters from the samples at the first sampling rate. A decimator component generates subsampled values for the plurality of input parameters at a second sampling rate, which is slower than the first sampling rate. An adaptive plant estimator component generates a model of the system based on the subsampled values. A compensator design component determines compensator parameters based on the model. The compensator parameters reflect changes in the system and are sampled at the second sampling rate. A feedback compensator adjusts the input signal to the system based on the compensator parameters.
