摘要： A method for current measurement in a switching converter is described herein. In accordance with one embodiment, the method includes switching a first transistor on and off in accordance with a logic signal, wherein a load current passes through the first transistor while it is switched on. The method further includes providing—by a second transistor—a sense current that is indicative of the load current, wherein the second transistor is coupled to the first transistor so that the first and the second transistors are switched on and off simultaneously. Further, the method includes determining an end of a switch-on phase of the second transistor, and providing a current sense signal that represents the sense current between a first time instant, which corresponds to the determined end of the switch-on phase, and a second time instant, at which the logic signal signals a switch-off of the first transistor.

摘要： A rectifier device is described herein. In accordance with one embodiment, the rectifier device includes a semiconductor body doped with dopants of a first doping type and one or more well regions arranged in the semiconductor body and doped with dopants of a second doping type. The rectifier device further includes a controllable resistance circuit that is electrically connected between the semiconductor body and a first well region of one or more well regions and configured to provide a resistive current path between the semiconductor body and the first well region. The resistance of the current path is dependent on an instantaneous level of an alternating input voltage.

摘要： A multi-channel device with a single diagnosis status pin may be configured to detect if one or more channels has a fault. The multi-channel device, which may operate within a system, can communicate which channel, of a plurality of channels, has the fault using only a single diagnosis status pin and no additional diagnosis control pins. The multi-channel device may output a fault signal on the diagnosis status pin and in response to an interrogation input signal on the same channel as a fault channel indicate to the system which channel is the fault channel.

摘要： A rectifier device includes a first transistor having a load current path and a diode connected in parallel to the load current path between an anode terminal and a cathode terminal. An alternating input voltage is operably applied between the anode terminal and the cathode terminal. A control circuit is coupled to a gate terminal of the first transistor and configured to switch the first transistor on for an on-time period, during which the diode is forward biased. A clamping circuit is coupled to the gate terminal of the first transistor and configured to at least partly switch on the first transistor while the diode is reverse biased and when the level of the alternating input voltage reaches a clamping voltage. The clamping circuit includes an additional circuit coupled between the cathode terminal and the gate terminal and configured to provide a voltage dependent on a load current.
