摘要： A multiphase DC-DC converter including at least one conversion path, multiple switch capacitance networks, and a multiphase switch controller. Each conversion path includes first and second intermediate nodes. Each switch capacitance network includes a capacitance coupled in parallel with an electronic switch and is coupled to one of the intermediate nodes. The switch controller controls the switch capacitance networks using zero voltage switching. Multiple phases may be implemented as multiple conversion paths each having first and second intermediate nodes coupled to first and second switch capacitance networks, respectively. A single conversion path may be provided with multiple switch capacitance networks coupled to each intermediate node for multiple phases. Alternatively, a common front end with a first intermediate node is coupled to one or more switch capacitance networks followed by multiple back-end networks coupled in parallel for multiple phases. A regulator may be provided to regulate an output voltage.

摘要： A four-switch step-down storageless DC-DC converter is provided having simultaneously ultra high efficiency of over 99% in an ultra compact size, while also providing a regulation and maintaining fast transient response while in regulation. Because of its storageless feature it is ideal for demanding computer applications, such as VRM (Voltage Regulator Modules), with extremely fast step-load load current change requirements and tight output voltage regulation requiring ultra low output ripple voltages during the transients.

摘要： A power supply includes a supply inductor and a first capacitor coupled to form a resonant circuit to generate a resonant waveform in a resonant operation, during a first portion of an operation cycle of the power supply. A charge storage element develops an output voltage to energize a load. A rectifier is coupled to the charge storage element and to the resonant circuit and is responsive to the resonant waveform for applying the output voltage back to the resonant circuit to interrupt the resonant operation, at an end time of the operation cycle first portion, when the resonant waveform produces a first change of state in the rectifier. A first sensor senses when the first change of state in the rectifier occurs. A source of a supply current is coupled to the rectifier and rectified in the rectifier to produce a rectified current that is coupled to the charge storage element to replenish a charge therein, during a second portion of the operation cycle. A switching transistor is responsive to an output signal of the first sensor for enabling the supply current to be coupled to the rectifier, during the operation cycle second portion, and for disabling the supply current from being coupled to the rectifier, during the operation cycle first portion.
