摘要： A switched mode power supply converter comprises a circuit pulse matching circuit configured to negate output voltage disturbance or noise during switching operation of a power conversion. The current pulse matching circuit input is driven by, or from, a power converter switch node of the switched mode power supply converter. The current pulse matching circuit comprises a rate-of-voltage change detection circuit driven by the power converter switch node.

摘要： An integrated switching regulator device has a switching mode regulator comprising an input voltage source and a switching circuit coupled to the input voltage source configured to generate a pulsed voltage from the input voltage. A low pass filter is coupled to the switching regulator and is configured to filter the pulsed voltage to provide a regulated voltage to a load. The low pass filter comprises at least two LC stages, wherein the first LC stage comprises an air cored inductor and each subsequent LC stage comprises a non-air cored inductor. The switching circuit comprises two or more switching elements configurable to operate at a switching frequency of several megahertz.
