  • Current threshold detection in synchronous regulation
    Patent number: 9948183
    Abstract: A synchronous regulator controller, including a synchronous switch that is coupled between a first node and a second node. The controller also includes a first voltage divider that includes a first resistive device that is coupled between the first node and a third node, and a second resistive device that is coupled between the third node and a second node. The controller also includes a comparator having a first input that is coupled to the first node, and a second input that is coupled to a forth node. The controller also includes a current source that is arranged to provide a current to the fourth node. The controller also includes a third resistive device that is coupled between the third node and the fourth node.

  • Current sensing circuit arrangement for output voltage regulation
    Patent number: 9024678
    Abstract: A circuit arrangement including a first transistor, a second transistor and a third transistor. The first transistor and the second transistor are configured so that the current flowing through the first transistor is proportional to the current flowing through the second transistor and the third transistor. The first transistor, the second transistor and the third transistor are configured to operate in an ohmic mode. The second transistor and the third transistor are coupled in series to each other. The first transistor, the second transistor and the third transistor match each other in at least one characteristic.
