  • Enhanced peak current-mode pulse-width-modulated (PWM) switching regulators
    Patent number: 9600063
    Abstract: A system, switching regulators, and methods of control for enhanced peak current-mode PWM switching regulators are disclosed. For example, a switching regulator is disclosed, which includes a master controller circuit and a slave controller circuit coupled to the master controller circuit, wherein the slave controller circuit is configured to generate a ripple current at a first ripple node, and a sensor circuit is configured to sense the ripple current at the first ripple node and convey the sensed ripple current to a second ripple node in the master controller circuit. In some implementations, the switching regulator is part of a power subsystem formed on one or more semiconductor ICs, wafers, chips or dies.
