  • Patent number: 9618540
    Abstract: A current sensing module and a power conversion apparatus and an electronic apparatus using the same are provided. The current sensing module is suitable for detecting a first load current flowing through a first load. The current sensing module includes a sampling stage circuit and an output stage circuit. The sampling stage circuit couples across the first load and selectively exchanges coupling nodes between the sampling stage circuit and the first load by a multiplex switching means, so as to sample the first load current flowing along a first direction or a second direction, and thus generate a sampling signal. The output stage circuit is coupled to the sampling stage circuit and switches coupling nodes between the output stage circuit and the output terminal of the sampling stage circuit, so as to generate a current indication signal indicating the magnitude of the first load current according to the sampling signal.

  • Patent number: 9413262
    Abstract: A smart power adaptor and a method of controlling power supply thereof are provided. The smart power adaptor includes a power conversion circuit and a control unit. The power conversion circuit is configured to convert an alternating current (AC) power into a direct current (DC) power for providing to a load device. The control unit is coupled to the power conversion circuit. The control unit is configured to apply a corresponding power-supply control mean according to a power state through communication of a charging communication protocol of a battery module of the load device to control an operation of the power conversion circuit, so that the power conversion circuit uses different power conversion behaviors to generate the DC power in response to changing of the power status.

  • Patent number: 9268348
    Abstract: A reference power generating circuit and an electronic circuit using the same are provided. The reference power generating circuit includes a first bandgap reference circuit and a second bandgap reference circuit. The first bandgap reference circuit is biased by a power voltage to generate a first reference voltage, where the first reference voltage has a first offset. The second bandgap reference circuit is connected to the first bandgap reference circuit in series and receives the first reference voltage generated by the first bandgap reference circuit. The second bandgap reference circuit is biased by the first reference voltage to generate a baseline reference voltage. The baseline reference voltage has a second offset, and the second offset is smaller than the first offset.
