Enpirion’s Newest DC-DC Converter Advances the Company’s Leadership in Power Management for Embedded Computer-on-Modules

Enpirion, the leading innovator of the industry’s smallest point-of-load DC-DC converters, announced a new member of its power IC portfolio targeted at embedded computing as well as solid-state drives (SSDs). The Enpirion EN5339 3 Amp power system-on-a-chip (PowerSoC) integrates the controller, power MOSFETs, compensation network and inductor into one highly compact solution that significantly reduces the traditional engineering analysis and design effort associated with discrete DC-DC converter designs. Its small solution footprint and slim profile offers Enpirion’s wide base of customers – who develop diverse form factors such as Ultra COM Express, PC104, Qseven, ATCA Advanced Mezzanine Cards (AMC), Compact PCI and others – an important new alternative. The EN5339 has already landed more than 20 design wins ahead of its official market release.

“Enpirion’s portfolio of PowerSoCs supports our hardware designers in easing the process of bringing to market numerous platforms, form factors and capacities,” said Jonathan Hinkle, memory system architect, Viking Technology, a leader in SSD, DRAM and hybrid technologies for the enterprise storage market. “The EN5339 is a nice addition to Enpirion’s lineup and helps streamline our power design efforts by eliminating cumbersome steps and needless iterations.”

The EN5339 fits into a 55 mm2 solution area with a 1.1 mm profile – setting the bar for the smallest 3 Amp solution available. High-density embedded computer-on-modules, in particular, require this small area and often a low profile to enable bottom-side PCB mounting. Keeping up with the demands of embedded, industrial and storage applications, the EN5339 enables a 20 percent solution footprint reduction and 40 percent lower profile compared to previous Enpirion 3 Amp products.

“We continue to optimize solution size and cost without compromising the high performance and simplicity of design inherent in all Enpirion’s PowerSoCs,” said Mark Cieri, Enpirion’s director of marketing and business development. “I was told just last week by a hardware engineering manager at a leading European embedded computer maker that his most difficult design challenge was fitting both the processors and discrete DC-DC converters onto the same card. He was delighted that we could solve his concerns.”

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
