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.
