  • Patent number: 8502516
    Abstract: A voltage regulation module coupled to a power conversion module to form a closed loop. The power conversion module includes a PWM circuit and a conversion circuit. The conversion circuit includes serially coupled first and second power switches. The PWM circuit outputs a drive signal to control the first and second power switches to cause the conversion circuit to generate an output current. The voltage regulation module includes subtraction and regulation circuits. The subtraction circuit obtains a voltage related to the output current, and performs a subtraction operation on this voltage and a reference voltage to generate a second regulation voltage. The regulation circuit generates a level voltage, which is directly proportional to the output current, according to the second regulation voltage. The PWM circuit adjusts a voltage level of the drive signal according to the level voltage so that this voltage level follows the output current.

  • Publication number: 20130144456
    Abstract: A method for starting an application smartly and power-efficiently is applicable to a portable electronic device installed with an application and hardware. The portable electronic device receives a voltage generated from a power supply, such as an internal battery power or an external power. After the portable electronic device has started, a connection between the application and the hardware is created. Upon detection that the voltage originates from the external power, the application is executed based on a preset schedule to start the hardware corresponding to the application until it is detected that the source of the voltage has been switched to the internal battery power. Upon the detection that the source of the voltage has been switched to the internal battery power, a user determines whether to change the state of use of the hardware, thereby rendering the portable electronic device smart and power-efficient.
