摘要： A phase current sharing network for a current mode multiphase switching regulator. The multiphase switching regulator includes switching networks for developing phase currents of switching phase networks controlled by pulse control signals for converting an input voltage to an output voltage. The regulator develops the pulse control signals based on current control values and at least one trigger value. The phase current sharing network includes conversion networks and a phase current combining network. Each conversion network provides a phase current value based on a corresponding phase current, such as by directly or indirectly measuring real current or by synthetically developing the phase current value. The phase current combining network develops an average phase current value based on the phase current values, and subtracts the average phase current value from each phase current value to provide the current control values used to control the switching networks.

摘要： A controller for a switching regulator is disclosed including a sense circuit, an error amplifier circuit, a filter and reference circuit, and a comparator circuit. The switching regulator includes a pulse switch circuit coupled to an output inductor for developing an output voltage. The sense circuit provides a sense signal indicative of current through the output inductor. The error amplifier circuit develops an error signal indicative of error of the output voltage. The filter and reference circuit high pass filters the sense signal to provide a filtered sense signal, and references the filtered sense signal and the error signal to a common DC level. The comparator circuit develops a pulse control signal used to control switching of the pulse switch circuit based on comparing the error signal with the filtered sense signal.

摘要： A steady state frequency control circuit for a variable frequency regulator including an open loop frequency control circuit, a frequency detector and a comparator circuit. The variable frequency regulator provides a clock signal indicating actual operating frequency and has a frequency control parameter for adjusting steady state operating frequency. The frequency detector receives the clock signal and provides a frequency sense signal which is compared with a steady state frequency reference signal to provide a frequency adjust signal. The frequency control parameter is adjusted by the frequency adjust signal to control steady state frequency. A method of controlling steady state frequency of a variable frequency regulator includes using open loop frequency control, determining the operating frequency and providing a frequency sense signal, comparing the frequency sense signal with frequency reference signal and providing a frequency adjust signal, and adjusting the frequency control parameter based on the frequency adjust signal.
