Abstract: A circuit configuration has a load transistor and a current measuring configuration. A method ascertains a load current through a load transistor. The circuit configuration includes a first and a second current sensor with a current measuring transistor in each case. Each of the current sensors provide a current measurement signal that is fed to an evaluation circuit. The evaluation circuit provides, from the first current measurement signal, a current measurement signal that is dependent on the load current. The load transistor and the current measuring transistors are preferably integrated in a common semiconductor body having a multiplicity of transistor cells of identical construction. The evaluation circuit preferably accounts for the spatial position of the cells of the first and second current measuring transistors in the cell array.

Abstract: A current/voltage converter arrangement is proposed, in which a first switch device (T1) with a first diode (TD1) is provided between a first input terminal (TE1) of a primary side (TP) of a transformer device (T) provided and a first input terminal (E1) of an input region (E), in which a second switch device (T2) with a diode (TD2) is provided between a second input terminal (TE2) of the primary side (TP) and a second input terminal (E2) of the input region (E).

Abstract: A semiconductor component contains two semiconductor bodies, which are spatially separated from one another and electrically interconnected. A compensation MOS field effect transistor is provided as the first semiconductor body, and a silicon carbide Schottky diode is provided as the second semiconductor body. Consequently, the semiconductor component can advantageously be produced significantly more compactly and more cost-effectively, since both the compensation MOS field-effect transistor and the silicon carbide Schottky diode contribute to a significant reduction of power loss.

Abstract: A switching regulator has a drive circuit, receiving an intermediate circuit input voltage, an output voltage of an intermediate circuit capacitor and an output current at a current measuring element and controls the electrical output parameters and the power factor of the switching regulator in accordance with an adjustable desired value by controlling the duty ratio of a power switch. The drive circuit has a start circuit for dynamically increasing a current limiting level for the power switch during a start time after the switch-on instant of the switching regulator from an initially low level up to a current-limiting desired level at the end of the start time. The loading current-time integral for the diode and the power switch of the power factor correction circuit of the switching regulator is the least with this soft start circuit. Moreover, noise due to abrupt magnetic driving of the inductor is avoided.

At least one capacitive element having a first electrode, a second electrode and a dielectric is provided in an integrated manner in the housing element or in the region thereof. The electrode regions of the capacitive element are electrically contact-connected to terminal regions of the semiconductor component, in such a way that high-frequency interference signals between terminal regions can be suppressed.

Abstract: Electronic components such as semiconductor chips are supported by the manufacturer by providing product developers an online catalogue with the electronic components that are available from the manufacturer. The novel support system links information typically provided on data sheets with application-specific information. The user is prompted to input the application-specific parameters in an interactive application note and the system provides information concerning the electronic component in the specific application context. The virtual support system thus provides interactive application notes with a detailed product description in a specific application context and with interactive entry fields, in addition to static data sheets and static application notes.
