The present invention provides an electrically isolated acquisition of a measurement signal by means of a measurement probe. For this purpose, a probe arrangement is provided with a probe head for electrically measuring a signal. The probe head is coupled to a probe coupler via optical links. In particular, optical links are used for power supply of the probe head and for forwarding optical signals corresponding to the measured electrical signal.

Probe head, probe coupler and probe arrangement

A multi chip module having a current sensing circuit and a semiconductor half bridge configuration having two vertically stacked field effect transistor dies that are connected by horizontally extending tap clips at respective opposite sides of their channels, wherein the current sensing circuit is coupled to two checkpoints, at least one being located on one of the tap clips so as to measure a voltage drop over a predetermined portion of the tap clip acting as a shunt resistor for sensing a current that is provided to a switching node of the half bridge configuration.

Multi chip module, method for operating the same and DC/DC converter

An electronic device is provided that includes a protection circuit for a light-emitting device. The protection circuit comprises a first node adapted to be coupled to an anode of the light-emitting device and a second node adapted to be coupled to a cathode of the light-emitting device. A voltage detection stage is coupled between the first and second nodes. The voltage detection stage is adapted to detect an overvoltage condition between the first and second nodes. Furthermore, the protection circuit comprises a thyristor coupled with its anode to the first node, its cathode to the second node to the voltage detection stage. When the overvoltage condition is detected in normal operation the thyristor is controlled to open so that the current can flow through the thyristor.

A DC-DC buck converter comprises a high-side power FET having a current path connected in series between an input terminal and an inductor connected to an output terminal supplying an output current to a load. The converter further comprises a low-side power FET having a current path connected between a reference terminal and an interconnection node of the high-side power FET with the inductor. The converter has a pulse width modulation controller receiving a feedback signal from the output terminal and providing pulse width modulated signals, and a gate driver circuit that receives the pulse width modulated signals from the pulse width modulation controller and applies pulse width modulated drive signals to the gates of the power FETs. The gate driver circuit supplies the drive signals to the gates of the power FETs at a variable voltage level adjusted in response to at least the output current, minimizing the power dissipation of the gate driver circuit.
