CONTROL METHOD FOR SUPPLYING POWER
First Claim
1. A control method for supplying power to an electronic system through a first power regulator, wherein the first power regulator supplies a first current and an output voltage to the electronic system and the electronic system includes a second power regulator and a load, the second power regulator being coupled between the first power regulator and the load, and the second power regulator receiving the first current and supplying a second current to the load;
- the control method for supplying power comprising the steps of;
increasing the output voltage and detecting the second current;
determining whether the second current suddenly drops as the output voltage increases;
when the second current suddenly drops, defining a level of the output voltage which corresponds to a starting point of the sudden drop of the second current as a first upper limit; and
setting the output voltage to be lower than or equal to the first upper limit.

Abstract
In a control method for supplying power, a first power regulator supplies a first current and an output voltage to a second power regulator and the second power regulator supplies a second current to a load. The method includes: increasing the output voltage and detecting the second current; determining whether the second current suddenly drops as the output voltage increases; when the second current drops, defining a level of the output voltage which corresponds to a starting point of the sudden drop as an upper limit; when the output voltage increases but the second current neither increases nor suddenly drops, defining a level of the output voltage corresponding to a point where the second current stops increasing as a lower limit; and setting the output voltage to be lower than or equal to the upper limit, and higher than or equal to the lower limit.
