Abstract: A method and apparatuses for power regulation using an extended current limit are disclosed. The power regulator detects an occurrence of an output current of the regulator exceeding a first current limit, triggers an extended current limit timer based on the detected occurrence, regulates the output current according to a second current limit higher than the first current limit based on a duration of the extended current limit timer, and regulates the output current according to the first current limit based on an expiration of the duration of the extended current limit timer.

Abstract: An apparatus and method for to incrementally reduce (e.g., de-rate) a power supply voltage output (VOUT) of a regulator to multiple subsystems in response to detecting high power conditions in a client device is described. In one instance, multiple low power client devices and a high power consumption client device are coupled to a power grid of the power management system with a power management integrated circuit (PMIC) supplying power to the power grid. The PMIC includes a buck-or-boost switching regulator including a load current adjustment device to de-rate the high power consumption device when a sum of the current consumed by the high power consumption device and the low power client devices is above a predetermined threshold.
