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.

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.

Bipolar 2-channel stepping motor driver

Toshiba Electronics Europe has launched a bipolar, 2-channel stepping motor driver rated for a high voltage of 40V and currents of up to 2.0A. The TC78S122FNG has been designed to save space, reduce power consumption, lower heat dissipation and minimise vibration and acoustic noise in high-speed motion control designs. Target applications include surveillance cameras, ATMs, office automation equipment, factory automation and home appliances.

Step down switching regulator

A 1.5A, 42V input synchronous step down switching regulator from Linear Technology delivers 93% efficiency when switching at 2MHz. This, says the developer, enables designers to avoid noise sensitive frequency bands.

2W DC/DC converter family

The NXE2 series of 2W surface mounted DC/DC converters from Murata Power Solutions is said to be footprint compatible with similar 1 and 2W devices available on the market. Measuring 12.5 x 4.4 x 10.4mm, devices in the NXE2 series are said to provide more power output from the same space as competitive parts.

New wide input voltage automotive buck regulators

Allegro MicroSystems Europe has developed two new adjustable high frequency DC-DC step-down switching regulators, both come with an integrated high-side power MOSFET. The A8586 provides up to 3.5 A output current; while the A8587 has output current of up to 2.0 A.

Power supply range targets rugged networked applications

Diamond Systems has extended its line of Jupiter-MM-5000 high-efficiency, high-precision DC/DC power supply modules. The latest, intelligent members of this rugged power supply family are claimed to offer up to 218W of 5, 12, and 3.3Vdc power in either the compact PC/104 or the PC/104-Plus form factor and an advanced system controller for complete software control of all power supply functions.

IDT expands power portfolio with dual-phase high-performance digital power controller

Integrated Device Technology (IDT) has introduced a high-performance dual-phase digital power controller that it says can help designers optimise, monitor and control high-power supply systems. The second-generation ZSPM1363 digital PWM controller is claimed to deliver high performance and transient response, suiting it for addressing the growing demands in the telecommunications, server, storage, FPGA and infrastructure markets.

MOSFET cuts conduction, switching losses

Said to be the flagship device in Fairchild’s 100V N-channel power MOSFET range, the FDMS86181 delivers improvements in efficiency, reduced voltage ringing and lower EMI in power supplies, motor drives and other applications requiring a 100V MOSFET.

AC to PoL development kit

An AC to point-of-load development kit from Vicor is said to enable power system designers to quickly evaluate a complete power system solution. The kit consists of an AC Front End chassis, which can deliver up to 400W via an isolated and regulated distribution bus voltage, and a point-of-load chassis (PoL), which generates three independent regulated PoL outputs. According to Vicor, the kits include all necessary ancillary components, including a bus hold up capacitor assembly and an AC line cord.

Axial metallised polyester and polypropylene film capacitors

Components Bureau has introduced the JFG series of axial lead, metallised polyester and polypropylene film capacitors from jb Capacitors to the UK market. The compact capacitors are said to feature high-temperature resistance, large capacity and good self-healing properties, they are suitable for use in instrument applications and DC and AC circuits of household equipment, as well as the fractional frequency circuit of acoustic systems.

CoolMOS CE package is cost-effective drop-in replacement for DPAK

Infineon Technologies is expanding it CoolMOS CE portfolio with a SOT-223 package. This package is claimed to offer a cost effective alternative to DPAK as well as space savings in some designs. The SOT-223 package without middle pin is said to be compatible with a typical DPAK footprint and can be used as a drop-in replacement for DPAK for designs in LED lighting and mobile charger applications.

Three-phase brushless motor driver with sine wave drive

Toshiba has unveiled the TC78B016FTG, a three-phase brushless motor driver IC that is claimed to achieve high efficiency and minimal noise at a range of rotational speeds without any need for phase adjustment. The TC78B016FTG is optimised for use in the small fan motors found in home appliances and industrial equipment.

Power control processor

Analog Devices claims further advances in digital processing are needed to unlock the full potential of inverters. Looking to meet this need, it unveiled the ADSP-CM41x control processor.
