Non-isolated Up Converters Support
High-Performance GPUs
  
 
2 MHz with ZVS and ZCS, the NBM provides low output impedance and Megahertz-fast transient response to dynamic loads. The NBM incorporates hot-swap and inrush current limiting.
 

The NBM supports state-of-the-art 48 V input GPUs using Power-on-Package ("PoP") Modular Current Multipliers ("MCMs") driven from a 48 V node sourcing a small fraction (1/48th) of the GPU current. Current multiplication overcomes the power delivery boundaries imposed by traditional 12 V systems standing in the way of higher bandwidth and connectivity.  
      
 
Preventing IoT Edge Device Vulnerabilities

 Security issues around IoT edge devices are rarely mentioned in the literature. However, the projected billions of IoT edge devices out in the wild makes for a vast attack surface.
 
Should hardware designers be concerned about security for IoT edge devices? And, is it worth the effort and cost to ensure security at this level? Mentor's Jim Miller explores internal design vulnerabilities and 3rd-party attacks on IoT edge devices in this white paper in order to answer those questions.

Eval Board for Half-Bridge SiC Power Modules
 
Analog Devices, in collaboration with Microsemi, has introduced a high power evaluation board for half-bridge SiC power modules with up to 1200 V and 50 A at 200 kHz switching frequency. The isolated board is engineered to improve design reliability while also reducing the need to create additional prototypes; saving time, lowering cost and decreasing time to market for power conversion and energy storage system designers.
The board can be used as the building block of more complex topologies, such as full-bridge or multi-level converters, for complete bench debugging of customer solutions. It can also function as a final evaluation platform or in converter-like configuration for full test and evaluation of Analog Devices' ADuM4135 isolated gate driver with iCoupler digital isolation technology and LT3999 DC-DC driver in a high-power system.

Step-Down Converters Target Always-On Car Systems
 
Maxim Integrated Products has announced the ultra-compact, pin-compatible MAX20075 and MAX20076 step-down converters that enable system designers looking to create small and highly efficient 40-V load dump-tolerant applications. The MAX20075 and MAX20076 step-down converters offer low quiescent current (IQ) and feature integrated compensation. This enables minimal external components that can lead up to 50% savings in board space making them well-suited for always-on automotive applications.

According to Maxim Integrated, car customers expect always-on applications to bring them experiences richer and more compelling than ever before. However, car system designers are challenged with having to balance delivering advanced features with meeting size constraints, power-saving features and high efficiency.

The MAX20075 and MAX20076 in peak current mode draw just 3.5 µA in the low power operating mode, which is key to meeting the stringent OEM IQ consumption requirements of 100 µA per module. The converters enable low noise operation via pin-controlled spread spectrum and fixed 2.1 MHz operation to meet CISPR 25 Class 5 EMI compliance. An added advantage of the 2.1 MHz operation and internal compensation is that it lowers the solution size and the bill of materials (BOM) compared to a non-synchronous device that operates in the AM band.
    


 Win a Free Subscription to Circuit Cellar Magazine!
 
This week's newsletter raffle is for a 1-year free subscription to Circuit Cellar! Drawing ends at midnight this coming Friday. Circuit Cellar is the premier media resource for professional engineers, academic technologists, and other electronics technology decision-makers worldwide involved in the design and development of embedded processor- and microcontroller-based systems across a broad range of applications. 
 

And congratulations to last week's raffle winner, Jack M., who won a 2017 archive CD of Circuit Cellar magazine. Thanks to all who participated!

CUI's Power Group has announced a line of DC-DC converters ranging from 5 W to 40 W. The AE series, available in board mount, chassis mount and DIN rail mount configurations, offers power ratings of 5 W, 10 W, 15 W and 40 W with input voltages up to 1,500 VDC and input ratio ranges up to 10:1. Designed for reliable operation in renewable energy applications such as solar power equipment, wind turbines and electric charging stations, the new models feature 5,600 VDC input to output isolation and a wide operating temperature range up to -40 to +70°C at full load. The series is also rated to operate at up to 5,000 meters, allowing it to support remote, high altitude installations.

These new isolated DC-DC converters are housed in fully encapsulated packages for use in harsh environments with measurements beginning at 2.75" x 1.89" x 0.93" (70 mm x 48 mm x 23.50 mm). Output voltage options of 5-, 9-, 12-, 15- and 24-VDC are available, depending on the series, including efficiency ratings up to 84%. Protections for over voltage and over current as well as continuous short circuit with automatic recovery come as standard.

Compact 250-V EMC Filters Deliver 6 A to 30 A 

TDK has announced the introduction of the TDK-Lambda RSEV series of EMC filters, with a voltage of 250 VAC/VDC and a choice of 6-, 10-, 16-, 20- and 30-A currents ratings. The RSEV has an integrated touch-resistant terminal block with recessed, captive screws. Hardware cannot be misplaced or dropped inside the system enclosure. The filters are suitable for general purpose use in a wide range of industrial and communications equipment.

The RSEV series is chassis mountable, or, with an optional kit, can be attached to the industry standard DIN rails. The maximum weight is 150 g for the 30 A model.  All models share a common package size of 85 mm x 39 mm x 30 mm 
(L x W x H), a 37% reduction in size compared to previous models (RSEN 30A). The filters have an operating ambient temperature rating of -25 to +85°C with derating above 55°C.
