22 Nov 2000TL;DR: In this article, a switching DC-DC converter unit is described that includes an input for receiving a first DC voltage from a DC power source and switching circuitry coupled to the input to generate a switched alternating voltage from the first voltage.
Abstract: A switching DC-DC converter unit is disclosed that includes an input for receiving a first DC voltage from a DC power source and switching circuitry coupled to the input to generate a switched alternating voltage from the first DC voltage. The switching circuitry includes a plurality of semiconductor switches having respective gate, source and drain leads, and further including noise suppression elements disposed on the drain leads. The unit further includes transformer circuitry coupled to the output of the switching circuitry and conversion circuitry disposed at the output of the transformer circuitry to convert the switched alternating voltage to a second DC voltage.

19 Oct 2007TL;DR: In this article, an automated test equipment interface system, e.g., for attaching a handler to a test head, includes a device interface board assembly including a stiffener frame having a frame body, alignment brackets connected to the frame body.
Abstract: An automated test equipment interface system, e.g., for attaching a handler to a test head, includes a device interface board assembly. The device interface board assembly includes a stiffener frame having a frame body that is configured for attachment to a test head, alignment brackets connected to the frame body, and cam followers connected to the alignment brackets. The system also includes a docking device. The docking device includes a docking plate that is configured for attachment to a handler, pull-down ramps connected to the docking plate and movable between a retracted position and an extended position, an actuator operable to initiate movement of the pull-down ramps, and a coupling that translates movement of the actuator to corresponding movements of the pull-down ramps. The pull-down ramps can include cam surfaces that are configured to engage the cam followers of the device interface board assembly during movement between the retracted and extended positions to pull the device interface board assembly towards the docking plate.

19 Dec 1996TL;DR: In this paper, a printed circuit board tester incorporating hardware for fast capacitive measurements is presented, which includes an amplifier having an input and an output connected to probes that can contact points on the printed circuit boards.
Abstract: A printed circuit board tester incorporating hardware for fast capacitive measurements. The circuit board tester includes a digital signal processor that can both source and measure test signals. It also includes an amplifier having an input and an output connected to probes that can contact points on the printed circuit board. In use, the board tester is configured to place a capacitor on the printed circuit board under test in the feedback path of the amplifier. The digital signal processor generates a stimulus signal to the capcitor and the output of the amplifier is passed to the digital signal processor. The digital signal processor uses an adaptive filtering approach to determine convergence of the measurement, thereby minimizing measurement time. The arrangement is flexible and can be reconfigured to measure both large and small values of capacitance.

02 May 2001TL;DR: In this paper, a driver circuit has a timing circuit and a driver, and the driver has at least one input coupled to the output of the timing circuit to receive data signals and couple the output signals to a device under test.
Abstract: A driver circuit for use on an integrated circuit tester. In one embodiment, the driver circuit has a timing circuit and a driver. The timing circuit has two or more inputs to receive data signals at a first frequency and at least one output. The timing circuit generates a control signal having a second higher frequency and outputs signals based on the data signals and the control signal such that the output signals are independent of the effects of timing skew and timing jitter of the data signals. The driver has at least one input coupled to the at least one output of the timing circuit to receive the output signals and couple the output signals to a device under test.

08 Dec 2006TL;DR: In this article, the authors describe a U-shaped component that attaches to a conductive surface of a printed circuit board and is configured to substantially surround a lengthwise portion of an inductor on three sides of the inductor.
Abstract: Devices and methods for reducing stray magnetic fields from an inductor are disclosed. In some aspects, a device includes a substantially U-shaped component configured to attach to a conductive surface of a printed circuit board and configured to substantially surround a lengthwise portion of an inductor on three sides of the inductor.
