Linear Technology, a leading provider of battery stack monitoring ICs for electric and hybrid/electric vehicles, is demonstrating the industry’s first wireless automotive battery management system (BMS) concept car. This wireless BMS concept car, developed by Linear’s design partner LION Smart, combines Linear’s highly accurate battery stack monitors with its SmartMesh® wireless mesh networking products in a BMW i3, replacing the traditional wired connections between the battery packs and the battery management system.

Teledyne LeCroy launched two new products ¾ the RP4030 active voltage rail probe and an industry first MIPI System Power Management Interface (SPMI) serial decoder. The RP4030 probe measures small signal variations on a DC power/voltage rail, while the SPMI decoder monitors and correlates SPMI serial bus messages with DC power/voltage rail changes. These two products are ideal for testing line or battery-powered computing and embedded systems that use digital power management ICs (PMICs) to reduce power consumption and increase system efficiency.

Elma Electronic now offers a vastly expanded selection of power supply solutions and significantly expanded technical expertise to its customers in the American markets, as a result of its 2015 acquisition of Trenew AG.

Murata has announced the MYMGK series of miniature “Mono Block” type surface mount point-of-load (PoL) DC-DC converters. These non-isolated “Mono Block” type converters are available in two models, a 6 Amp and a 20 Amp. Each version is available with two output voltage range options. Typical applications for these converters include powering FPGAs and CPUs used in data, telecommunications, and networking communications equipment, and in equipment using distributed bus architecture.

Analog Devices, Inc. (ADI) today introduced a highly integrated polyphase analog front end (AFE) with power quality analysis designed to help extend the health and life of industrial equipment while saving developers significant time and cost over custom solutions. Achieving extremely accurate, high-performance power quality monitoring typically requires customized development, which can be expensive and time-consuming.

In many measurements, connections to the Device Under Test (DUT) is very important and can fundamentally determine whether the data we get is correct or not, whether the result is useful or potentially misleading.  This article highlights some of the main items to consider.  To illustrate the points, we use examples with DC-DC converter evaluation boards.

In today’s ever-changing PCB requirements arena, DC drop caused by IR losses are becoming a bigger concern for design engineers. Along with the IC currents demands increasing the currents carried on the PCB are rising as the voltages, and voltage margins, decrease. As the currents increase so do the heating effects of IR drop and their consequences to the PCB design. SIwave introduces a new solver type for design engineers to investigate preliminary thermal performance on designs.

Power Delivery Network(PDN) time domain noise analysis is an essential part for SI/PI/EMI analysis, SIwave can utilize CPM’s current PWL file as a current sink for transient analysis combed with C4 bump’s RLC parasitics to give more realistic and accurate noise value.

SIPro uses an innovative new composite EM-technology that delivers high-frequency accuracy, together with the speed and capacity required for densely-routed cutting-edge PCB design. The PIPro solution is a collection of three PI-specific simulation engines for DC IR drop, AC power delivery network (PDN) impedance, and power plane resonances analysis.

Keysight ADS 2016 features a host of new, technologies designed to improve productivity, including two electromagnetic (EM) software solutions specifically created to help signal and power integrity engineers improve high-speed link performance in PCB designs. What follows is a listing of 8 ways in which ADS 2016 can help you, the engineer, overcome your signal and power integrity challenges.
