Title: VOLTAGE REGULATING DEVICE
Abstract:
Disclosed is a voltage regulating device. The device comprises: a power management module for receiving the first current and generating the second current according to the first current, wherein the second current flows into the load and includes multiple second sub-currents; and a signal control module for controlling the cutoff and conduction of the multiple second sub-currents when the first current changes from the first value to the second value so as to adjust the time of the second current changing from the first value to the second value. The voltage regulating device provided by the embodiment of the present invention can change the voltage over both ends of the load from the value corresponding to the first value of the second current to the value corresponding to the second value of the second current slowly by adjusting the time of the second current changing from the first value to the second value, so as to insure that the deviation between the voltage over both ends of the load and the working voltage of the load is not big during the second current changing from the first value to the second value. Then the problem of excessive regulation in the prior art can be solved, and the performance of the electronic chip can be assured.
