Würth: MagI3C Power Module Reference Design
Waldenburg, Germany — MagI3C power modules
from Würth
Elektronik are DC-DC converters with integrated controller IC, induc- tors and capacitors. Using the “MagI3C Power Supply Reference
applications that require an adjust - able power source. The reference design generates a constant voltage with an adjustable maximum cur- rent on the one hand, or can be set to generate a constant current with adjustable maximum voltage on the other. In the two operating
modes, the output voltage can be set from 0 to 15V and the current from 0 to 2.5A. The input voltage range is 7 to 36V. LEDs on the board indicate the voltage regulation mode, cur- rent regulation mode and a missing output voltage. The output voltage and output cur- rent are conveniently set on two potentiometers. The reference design can

Design,” the manufacturer now demonstrates the ease with which an adjustable current or voltage source can be built with a MagI3C power module. The board is based on the MagI3C variable step down regulator module (VDRM) to which two addi- tional control loops have been added. The design is aimed at various

TDK Intros 250W DC-DC Converter
National City, CA — TDK has added 250W rated SIP (single inline pack- age) models to the TDK-Lambda i6A4W product family of non-isolated DC-DC converters. Utilizing less than 0.47 in.2 of board area, the new converters offer 60 percent space savings when compared with 1/16th brick format converters. Capable of operating from
a wide input voltage of up to 9 to 53V, the i6A4W step-down converters deliver an output voltage that can be adjustable from 3.3 to 15V or 3.3 to 40V. The i6A4W series can operate from existing 12, 24, 36, or 48V system voltages to generate additional high-power voltages in medical, communications, industrial, and test and meas- urement equipment. With efficiencies of up to 97.5
percent, power losses are minimized, allowing the products to operate in harsh ambient temperatures of –40 to +257°F (–40 to +125°C) even with low airflow requirements. The need for external output capacitance is reduced, due to an optimized dynam- ic voltage response, further reducing board space requirements. The basic feature models include an output voltage adjust-
ment pin, positive or negative logic remote on-off, remote sense, input under-voltage, over-current, and thermal protection. The full-featured models are equipped with a power

good signal, output voltage sequenc- ing and the ability to synchronize the operating frequency to minimize sys- tem noise. All models are certified to UL/CSA 60950-1, IEC/EN 60950-1 and carry the CE mark for the Low
Voltage and RoHS Directives. Contact: TDK-Lambda

NJ Micro Electronic Testing Inc. Presenting the One Source for Electronic Component Procurement, Testing, Upscreening and Counterfeit Detection HARTING: Rear
Mounting Options for Han Metal Housings
Elgin, IL —The metal hoods and hous- ings of HARTING’s Han® B, EMC and M series now offer rear mounting options for contact inserts. This option greatly simplifies the preassembly of interfaces for control cabinets. With the new Han metal hous-

and the Federal Aviation Administration FAA-AC-0056, AC00-56B Certification
ings, it is possible to lock the prefabri- cated inserts directly from the rear into the bulkhead mounting housing from the interior of a control cabinet. In the past, Han inserts had to be con- ducted from the inside of the cabinet through the panel cutout, before they could be preassembled outside. After that, they were pushed back and fixed into the bulkhead mounted housing. In the new metal hoods and
housings, the insulation bodies are inserted into a plastic holding frame that snaps safely into the aluminum die-cast enclosure, supported by a lug. In order to achieve protection in accordance with class IP65/66 and also to guard against the effects of UV radiation and ozone, the flange rubber seal is laid completely into the interior of the housings. The housings of the Han M
series were redesigned according to the same principles. The Han M hoods and housings differ from their Han B counterparts only by the fact that they are even more suitable for harsh environments, for example, on
the exterior of wind turbines. By the end of this year, rear
mounting inserts with continuous 360° degree shielding will also be available. With Han EMC, the

shielding is always on the metal hood or housing. The hoods also need spe-
cial EMC cable glands. Contact: HARTING North
