Circuit Device and Electronic Apparatus

摘要

Various embodiments may relate to a circuit device and an electronic apparatus. The circuit device may include a main circuit unit, an energy store and output unit and a valley detection unit. The main circuit unit transfers energy to the energy store and output unit according to a detected voltage of the valley detection unit. Furthermore, the circuit device described above also includes a malfunction processing unit for preventing the main circuit unit from transferring energy to the energy store and output unit by adjusting the detected voltage of the valley detection unit in the case that the energy store and output unit has an output malfunction. Hereby, elements in the circuit device may be prevented from being damaged by the output malfunction. Moreover, the circuit device has a simple structure and is cost effective.
