A load driving signal-linked high voltage driving method comprises the steps of: generating an output power voltage of preset size by boosting the voltage of input power; converting the output power voltage so that the generated output power voltage may be linked with an output signal of a load driving circuit; and driving a load by applying the converted output power voltage to the load driving circuit. According to the above present invention, it is possible to minimize power consumption of a battery in a portable electronic device which drives a load by converting the low-voltage rectification power or a voltage of the battery into a high voltage, and thus the usage of a function or an apparatus such as a haptic terminal or the like, which may need a high voltage, is more activated. |
