    Abstract: Described embodiments include a circuit for temperature sensing having a first current source coupled to a diode input terminal. The first current source provides a first current at a first current output. A second current source provides a second current at a second current output. The second current is larger than the first current. A first switch is coupled between the second current source output and the diode input terminal. A capacitor is coupled between the diode input terminal and a temperature output terminal. A second switch is coupled between the temperature output terminal and a ground terminal. The temperature output terminal provides a temperature signal having a voltage that is proportional to a temperature of a component.

    Abstract: Techniques for controlling a switching converter. In an example, the converter includes a switching element and a logic circuit. The switching element includes a plurality of parallel-coupled transistors. The logic circuit is configured to initially provide one or more gate drive signals to one or more of the parallel-coupled transistors, respectively, but not to all of the transistors. After a delay period, the logic circuit is further configured to provide a respective gate drive signal to all or an otherwise larger number of the transistors. The initially-provided one or more gate signals is/are based on one or more conditions associated with the converter, such as RdsOn associated with the switching element and/or temperature. In this manner, a switching transistor that is adaptively-sized based on the condition(s) is initially switched to damp ringing, and a larger switching transistor (e.g., all transistors in parallel) is subsequently switched for low conduction loss.

    Abstract: Transistor arrays are disclosed herein. An example transistor array includes a first node for coupling the transistor array to a circuit. A first transistor and a second transistor are coupled to the first node. A gate controller is coupled to the gate of the first transistor and the gate of the second transistor and is for selectively turning on the first transistor and the second transistor. A current source is coupled to the first node and is active when the second transistor is off. Calibration circuitry measures the voltage of the first node when the current source is active.
