    摘要: A method is described comprising conducting a first current through a switching transistor. The method also comprises conducting a second current through a pair of transistors whose conductive channels are coupled in series with respect to each other and are together coupled in parallel across the switching transistor's conductive channel. The second current is less than and proportional to the first current.

    摘要: Stepwise drivers for DC/DC converters are described herein. In one embodiment, a stepwise driver is provided to charge or discharge a gate capacitance of a power switch of a DC/DC converter. In a particular embodiment, a stepwise driver example includes multiple switching elements to sequentially switch to charge a gate capacitance of a power switch of a DC/DC converter from a first voltage to a second voltage in multiple steps. Other methods and apparatuses are also described.

    摘要: A system may include detection of a direction of transistor body current flow, and control of a regulator transistor to regulate a transistor body voltage based on the detected direction. In some aspects, a first regulator transistor is controlled if the direction of current flow is into a transistor body and a second regulator transistor is controlled if the direction of current flow is out of the transistor body.
