omplex process and control technology is increasingly


gaining entry into electronic applications in the course of industry 4.0. This also involves the use of thermal management components, which are operated with DC voltage. Stego is focusing on this trend with DC Line items for


to supply an application is fundamental and influences the entire circuit layout as well as the component selection. DC supply, that is, the transformation of AC voltage in DC voltage before entering the enclosure for the supply of the internal components, is becoming increasingly prevalent in the course of industry 4.0 and more complex process and control. The electronics protectors from


Stego know these needs and have many years of experience with DC products in the segments of heating, regulating, cooling and lighting. Integrating its products into the DC Line takes this


development into account. The enclosure light LED 025 Ecoline with operating voltages from DC 24 -48V (min. DC 20V, max. DC 60V) and the Filter Fan Plus FPI/FPO 018 with DC 24V and DC 48V mark the start in the company’s DC Line. The LED 025 Ecoline lights in its


DC variants score with high fail- safety as well as long service life (60,000h). Glare-free brightness with daylight colour temperature (6,000 - 7,000K, 400 Lm at 120° beam angle) lead to true-colour illumination with low power consumption (5W). Mounting the compact LED lamp is easy with a choice between screw, clip or magnetic fixing. www.stego.de


PCB TERMINAL BLOCKS


Meeting the need for PCB terminal blocks for use in applications requiring higher current and voltage capabilities, distributor Switchtec has introduced Euroclamp’s MV series of high power terminal blocks. Not only are the terminals versatile in their


40A µMODULE REGULATOR WITH 3D STACKED-INDUCTOR PACKAGING


A 40A step-down µModule switching regulator has been released by Linear Technology with 3D construction for quicker heat dissipation and cooler operation in a small package. By stacking its inductor on top of a 16mm x 16mm BGA package, the LTM4636 benefits from the exposed inductor as a heat sink, permitting direct contact with airflow from any direction to cool the device. This device delivers 40W (12VIN


, 1VOUT , 40A, 200LFM) with only 40°C


rise over ambient temperature. Full-power 40W is delivered up to 83°C ambient and half-power 20W is supported at 110°C ambient. This device operates at 92%, 90% and 88% efficiency, delivering 15A, 30A and 40A, respectively, to a 1V load


). The µModule regulator is scalable, such that four in parallel current sharing mode deliver 160W with only 40°C rise and 88% efficiency (12VIN


(12VIN , 1VOUT , 400LFM). Device height is 7.07mm, including the inductor stacked on top of a 16mm x 16mm x 1.91mm BGA package.


In addition to dissipating heat from the top, it is designed to uniformly disperse heat from the bottom of the package to the PCB with 144 BGA solder balls, with banks of them assigned to GND, VIN


and VOUT where high


current flows. The LTM4636 µModule regulator benefits system designers with its enhanced thermal performance in a small package resulting from the combination of impressive DC/DC conversion efficiency and enhanced heat dispersion. www.linear.com/product/LTM4636


Molex has announced the launch of its PowerLife standard and custom wireless power coils with NuCurrent technology for plug-free device charging. The integrated wireless power coils feature high power transfer efficiency (Q-factor) and support low, high and proprietary frequencies, in standard and custom sizes. A high Q-factor results in lower heat generation and faster charging in a range of applications, including mobile phones, tablets, gaming systems, wearables and other consumer electronics, medical devices, furniture and in-vehicle transmitters. www.molex.com


range of power ratings, but also in terms of pitch size, embracing options of 5.08mm, 7.5mm, 7.62mm, 6.35mm, 9.52mm, 10.16mm, 12.7mm and 15mm. Some pitch sizes were chosen to address specific market needs and demands, whilst others were needed to meet the capacity and clearance requirements of the PCB pin and cables commonly used. These high power PCB terminals are available as standard in green. www.switchtec.co.uk


MEDICAL WALL MOUNT POWER SUPPLIES MEET LEVEL VI AND TIER 2 STANDARDS


A new series of medically-approved wall mount/plug top power supplies that meet the latest Department of Energy (DoE) Level VI and Code of Conduct (CoC) Tier 2 standards has been released by XP Power. The company’s ACM06 and ACM18 feature single outputs of 6W and 18W respectively and are claimed to use less energy while operating at no load to help reduce the impact on the environment and reduce energy costs. The power supplies feature a high average


efficiency of up to 87.5% typical measured at 25%, 50%, 75% and 100% load, meeting the new DoE energy efficiency level VI (US) and CoC Tier 2 requirements in the EU. Both series

feature a low no load input power, with all ranges consuming less than 0.075W. Exhibiting versatility, the ACM06 series is


available in 5, 9 and 12VDC output models, while the ACM18 comes in 5, 9, 12, 15, 18 and 24VDC single output models, the most common output voltages to suit most applications. Both offer a choice of detachable input plugs for either the US, UK, EU, China or Australian use. This gives the designer the option of sourcing one or multiple plugs for their specific locations. They have medical 60601-1 and ITE 60950-1 safety approvals, and meet Class B limits for both conducted and radiated emissions. www.xppower.com
