Within the world of electronics developments in Power can be crucial to design engineers. At New Electronics we are aware of the importance of staying abreast of the recent advances in and the impact it can have on your role, that’s why we have collated all the latest news in one place.

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.

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.

Redefining power-conversion efficiency

STMicroelectronics’ MDmesh DM2 N-channel Power MOSFET transistors are claimed to achieve greater efficiency in low-voltage power supplies for computers, telecom networks, industrial, and consumer devices.

How small diameter electrolytic capacitors in power supplies can impact reliability and cost

Recently a member of TDK-Lambda’s technical marketing team experienced first-hand just how much influence small diameter electrolytic capacitors can have on long-term power supply reliability. Unfortunately he picked February to have his central heating system upgraded and Britain’s unpredictable weather system delivered snow! The 7-year old boiler system in the loft had been turned off for two days while the radiators were replaced. When the installation was complete, the boiler was switched on, but failed to start.

Battery charger supports USB Type C connector

Said to be the industry’s first buck-boost battery charger that supports two-way power delivery using the reversible USB Type-C connector, Intersil’s ISL9237 Narrow VDC battery charger can replace buck and boost two chip charger solutions.

High temperature rated capacitors

Dielectric Laboratories (DLI), a Knowles brand, has announced a number of specification extensions to its ultra-low ESR and high Q MLC capacitors. In both cases the temperature performance has been increased to 175°C giving engineers more scope in their designs.

Multiple output power IC from Toshiba

A new general purpose system power IC with multiple outputs and functional safety circuits for automotive applications has been unveiled by Toshiba Electronics. The new TB9044FNG is housed in an HTSSOP48-P-300-0.50 package measuring 6.1mm by 12.5mm x 1.0mm.

Infineon’s S5 IGBT is efficient and robust

Infineon Technologies has released the S5 IGBT range, based on the ultra-thin wafer TRENCHSTOP 5 IGBT. This range has been developed specifically for AC/DC energy conversion in industrial applications switching up to 40kHz, typically to be found in Photovoltaic Inverters or Uninterruptible Power Supplies.

Power supplies for power hungry products

Luso Electronics has announces the availability of Qualstar’s N2Power branded efficient 76.2 x 127mm XL500 Series, available in 12, 24 and 48V output models. The compact devices are ideal for broadcast, storage and network products with applications in the industrial, gaming and instrumentation markets that require significant power.
