Abstract:
Embodiments include systems and methods for voltage regulation in a coupled inductor topology. Embodiments comprise a switching voltage regulator that is responsive to a light load signal from the device to which power is supplied. When the light load signal indicates that the device is not in a light load condition, the voltage regulator exhibits a low resistance to reduce I2R losses. When the light load signal indicates that the device is in a light load condition, the voltage regulator exhibits a higher resistance but lower capacitive losses within. In some embodiments, a first set of switches enables an inductor to charge through switches of the first set and a second set of switches enables the inductor to discharge through switches of the second set. The number of switches and their associated drivers in a set that are placed in a continuously-off state depends upon whether the device is in a light load condition or not.
