Title: POWER REGULATION DEVICE AND METHOD, CHIP SYSTEM AND METHOD FOR OPERATING CHIP SYSTEM
Abstract:
A power regulation device and method, chip system and method for operating the chip system. The power regulation device comprises a controller (21) and a digital-to-analog converter (22). The controller converts a voltage adjustment quantity fed back by a load chip (33) into a digital feedback voltage signal adapted to a power chip (31), and outputs the same to the digital-to-analog converter; the digital-to-analog converter converts the digital feedback voltage signal into an analog feedback voltage signal, and outputs the same to a power chip so as to regulate supply voltage. The power regulation device can be used to implement an adaptive supply voltage regulation function, thereby reducing the power consumption of a load chip.
