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.

Buck converter has high current density

A 12V, 10A, 10MHz series-capacitor buck converter from Texas Instruments is said to have a current density of more than 50A/cm3, four times more than any other 12 V power management component or solution available.

Low profile AC/DC supplies

The (M)WLP225 Series of 225W low profile AC/DC products is available from Gresham Power Electronics. Design by EOS and suitable for commercial, industrial and medical applications, the (M)WLP225 Series comes in a 2 x 4 x 1in package which the supplier says is suitable for use in rack enclosures.

Power management IC integrates three MOSFET stages

The XR77103 is Exar’s first universal power management IC to feature three integrated synchronous MOSFET power stages. This, says the company, results in an easy to use power management solution for a range of FPGAs, SoCs, DSPs and video processors

Accelerating adoption of wireless power in compact, low-power applications

Integrated Device Technology (IDT) has introduced a wireless power reference kit claimed to make integrating wireless charging into compact electronics easy and affordable. The IDT Qi-based transmitter and receiver reference kit targets designs requiring 3W or less, such as smartwatches, headphones, health and fitness trackers and portable medical devices.

Open frame DC/DC converters

Two open frame isolated DC/DC converter families have been unveiled by CUI. The PRD15 and PRD25 series provide 15W and 25W respectively, have a typical efficiency said to approach 91% and measure 28 x 24 x 8mm.

Innovative modular power solution

ABB has launched a scalable power distribution and protection solution for use in data centre applications. ABB’s MNS-Up solution integrates uninterrupted power supply (UPS) and switchgear technologies into a single, modular system, which is claimed to lower footprint by up to 30%, increase uptime, and reduce maintenance costs.

MagnaLOAD DC electronic loads 1.25 kW to 120 kW+

Magna-Power Electronics, a specialist in programmable DC power products, has released a new line of DC electronic loads. Spanning 1.25 kW to 120 kW+ the MagnaLOAD line includes 3 product series, ALx Series, ARx Series, and WRx Series spanning 39 air- and water-cooled models with voltage ranges up to 0-1,000 Vdc and current ranges up to 0-1,200 Adc.

Two-in-one MOSFETs for load switching in mobile devices

Toshiba has introduced the SSM6L61NU and SSM6N61NU two-in-one MOSFETs.These MOSFETs, are housed in compact SOT-1118 (UDFN6) packages, and are claimed to feature high heat dissipation and low drain-source ON-resistance. These features are said to make them suitable for use as power management switches and DC/DC converters in mobile devices, including smartphones and tablets. The SSM6L61NU and SSM6N61NU can also be used in battery management applications and for load switching in applications with USB Type-C interfaces.

Panasonic launches "PA-N Relay" for PLCs

Panasonic has developed and released a "PA-N Relay" that it claims will help PLC manufacturers to develop products that meet new safety standards. The relay is also expected to contribute to improved safety and reliability of industrial equipment.
