Abstract
Official abstract text for this publication.
A switching regulator including: a power stage having a first power switch and a second power switch coupled in series; a filter circuit having an inductor and an output capacitor; a feedback circuit configured to provide a feedback signal indicating an output voltage of the regulator; and a control circuit configured to provide a switching signal to control the ON and OFF of the first power switch so as to regulate the energy supplied to a load; wherein the control circuit has a peak current generator configured to generate a peak current signal, wherein the gain of a variation of the peak current signal between the contiguous switching cycles is less than one.
First claim
Opening claim text (preview).
We claim: 1. A switching regulator, comprising: a power stage having a first power switch and a second power switch coupled in series to receive an input voltage; a filter circuit having an inductor and an output capacitor, an output signal is provided across the output capacitor; a feedback circuit having an input terminal configured to receive the output voltage, and an output terminal configured to provide a feedback signal indicating the output voltage based on the output…
