Abstract
A voltage regulation method, a controller, and a chip are provided. In the method, a controller receives a digital first status representation value sent by a sensor; the controller determines, according to the first status representation value and at least one of a second status representation value or a first expected value, whether to regulate the supply voltage of the load, where the second status representation value represents a node voltage that is at a previous moment and that is of the detection point of the load, and the first expected value represents an expected value of a node voltage of the detection point; and when determining to regulate the supply voltage of the load, the controller sends a digital control signal to a power gating array, to control the power gating array to regulate the supply voltage.
