Power

Power electronics is a key element in the world of electronic design and engineering and electronic engineers need to have a thorough understanding of this area if they’re going to create successful products.

In this section, New Electronics keeps designers up to date with the latest developments in the power electronics market – everything from DC/DC converters to IGBTs to battery technology. In fact, New Electronics covers any power product that can go on a PCB.

Converter offers longer battery run times

ams has introduced a 1A synchronous buck converter with a wide input voltage range, high efficiency and low stand-by current. The device is said to suit designs powered by a single cell lithium-ion battery.

Delivering usable power at high temperatures

Artesyn Embedded Technologies has unveiled a new family of fanless, conduction-cooled AC-DC power supplies. The LCC600 series has been designed to deliver their full 600 Watt power output across a wide operating temperature range of minus 40 to 85 degrees Celsius.

Toshiba launches next-generation transistor arrays

Toshiba Electronics Europe has launched a new generation of efficient transistor arrays based on double diffused MOSFET (DMOS FET) technology. The new TBD62xxxA series is the successor to the company’s TD62xxxA series of bipolar transistor arrays, which have found wide use in applications including motors, relays and LED drives.

FTDI Chip adds graphic toolchain package to EVE offering

FTDI has sought to bring more support to its Embedded Video Engine (EVE) product offering with the introduction of the EVE Screen Designer - available now to download for free. Suitable for use with Windows operating systems (Windows 7 and above), this sophisticated, but easy-to-operate development suite has been developed to enable the creation of advanced human machine interfaces (HMIs), via EVE’s object-oriented approach, without any understanding of EVE display lists. This means that it is far more accessible to graphic designers who are concerned primarily with the look and feel of the HMI.

Next generation PMBus digital controller targets high-performance computing

Powervation has launched a high-performance digital DC/DC controller for FPGA, ASIC, and POL power for communications & computing applications. Designed for key rails that require precision output voltage regulation and tight control during transient conditions, the PV3105 digital controller provides low jitter and low output voltage ripple, and improved transient response, making it suitable for powering low-voltage, high current rails on leading process nodes for ASICs/FPGAs.

New 7kW 3-phase AC/DC power supply from Murata

Murata Power Solutions has unveiled the D2U5T-H3-7000 3-phase input hot-swappable AC/DC power supply. Fan cooled this efficient power supply, typically up to 95.5% overall efficiency at 50% full load, provides a 54 VDC main output at up to 7,000 Watts from a 480 VAC input.

andersDX delivers entry level Embedded UI

andersDX has created an entry level DX series embedded display platform with the launch of the DX1, based on the 600MHz ARM Cortex-A8 processor from Texas Instruments. The DX1a features an integrated TFT touch screen and is preloaded with Linux, Android or Windows CE. With the addition of application software, it becomes a fully working prototype system.

Fully encapsulated 50A digital power module from Intersil

Intersil has unveiled the ISL8272M, its first 50A fully encapsulated digital DC/DC PMBus power module. The device is a complete step down power supply that delivers up to 50A from industry standard 12V or 5V input power rails. Four modules can be combined to provide up to 200A.

Two phase 90A POL DC/DC module

Ericsson has launched a two phase 90A digital point of load (POL) DC/DC power module that offers compensation free performance and the ability to connect modules in parallel to provide up to 360A.

DC/DC converters feature non linear adaptive control

The iEH series of 300W 1/8th brick DC/DC converters from TDK-Lambda are said to use digital non linear adaptive control to improve dynamic response, system stability and reliability. This, says the company, makes the devices suitable for demanding applications, including communications and test and broadcast.

Synchronous buck switching regulator delivers 2A

The ISL8002B synchronous buck switching regulator from Intersil delivers up to 2A from a 2.7V to 5.5V input supply. Switching at 2MHz is said to provide better transient response, whilst features such as programmable soft start and output tracking and sequencing of programmable devices increase system reliability for point of load conversion.

New digital controllers come with programmability and digital features

Powervation has introduced a new series of digital DC/DC controllers for gaming & high-performance motherboards, embedded computing, networking, and telecom applications. The PV3203 & PV3205 digital dual-phase controllers offer fast transient response and a number of new features intended to improve power supply and system performance, while reducing overall bill of material component cost.

Intersil unveils synchronous buck regulator for FPGAs and MCUs

The new ISL8002B synchronous buck (step-down) switching regulator from Intersil has been designed to deliver up to 2A of continuous output current from a 2.7V to 5.5V input supply. Along with the device’s 2MHz switching frequency it provides additional programmable soft-start, and output tracking and sequencing of FPGAs and microprocessors, providing increased system reliability for point-of load conversions in networking, factory automation, instrumentation, and medical equipment.

Microchip LoRa technology looks to enable IoT

Microchip has launched the first in a series of modules for the LoRa technology low-data-rate wireless networking standard, which enables Internet of Things (IoT) and Machine-to-Machine (M2M) wireless communication with a range of more than 10 miles (suburban), a battery life in excess of 10 years, and the ability to connect millions of wireless sensor nodes to LoRa technology gateways.

EnOcean adds data encryption to wireless sensors portfolio

Energy harvesting wireless technology specialist, EnOcean, has added encrypted data communication to its complete range of energy harvesting wireless sensor modules. These security mechanisms can optionally be activated and prevent different types of attacks, including replay and eaves-dropping attacks or forging messages.
