Texas Instruments is one of the most dominant technology companies ever. Behind Intel and Samsung, it is the world’s third largest producer of semiconductors. In addition, they are the largest manufacturer of digital signal processors and analog semiconductors. Young students may just know of TI as producers of their world famous graphing calculators. However, for the older, more experienced students, they quickly learn TI has technology that can be found everywhere. In fact, many of the ICs used for basic electronics are all created by TI.

There is also one additional area TI’s technology excels at. That would be in energy efficient electronics. One of the more popular devices is the MSP 430 microcontroller family. These MCUs allow developers to create embedded applications, which can manage power extremely efficient. The CPU can work with speeds up to 25 MHz or can be lowered to save power in applications. More importantly, the MCU has a low power idle mode. When working in this mode the CPU will draw as little as 1 micro-Amp of current. Along with the low power capabilities, this MCU can also work with all the usual embedded electronics communication protocols and peripherals.

Company Hammond brings to market quality universal holders enabling to use your device even on a DIN rail. 

DIN rail has admittedly a lot of advantages and no wonder, that it became a very favourite „platformou“ for not only distribution boxes, but also for various alarms, centrals, and other devices even with a finer electronics.

Naturally, to attach an enclosure to a DIN rail it is necessary that the enclosure was directly designed for a DIN rail or it can be any other enclosure amended with a suitable holder (clip). DIN rail enclosures are usually the first choice, but their shape, size, material and other features aren´t always suitable for our concrete device. For these purposes we incorporated to our stock offer 4 new holders of the 1427DIN series. 3 types – 1427DIN42M, 1427DIN75M and 1427DIN100M are made of aluminium with an anodized surface and 1 type – 1427DINCLIP is form a rigid nylon (UL94-V0). All aluminium types are supplied including a screw, washer and nut for fastening to an enclosure. Aluminium types are constructed so that to attach or loosen from a DIN rail, no tool is necessary. A reliable fastening to DIN rail ensures a spring from a galvanized steel and to its release, it´s only necessary to press the clip from the bottom and to tilt the upper part from a DIN rail. An advantage of holders is, that they´re usable with various enclosures, even from other producers.

Detailed drawings can be found in datasheets at given types. On the Hammond website it´s also possible to find CAD files and 3D models. In case of interest in any HAMMOND products please contact us at info@soselectronic.com.

The LT3081 is a rugged 1.5A wide input voltage range linear regulator with key usability, monitoring and protection features. The device has an extended safe operating area (SOA) compared to existing regulators, making it ideal for high input-to-output voltage and high output current applications where older regulators limit the output. The LT3081 uses a current source reference for single resistor output voltage settings and output adjustability down to zero volts. Output current limit can be set externally with a single resistor. This regulator architecture, combined with low millivolt regulation, enables multiple ICs to be paralleled easily for heat spreading and higher output current. The current from the device’s current monitor can be summed with the set current for line-drop compensation, where the output of the LT3081 increases with current to compensate for line drops.

15W toroidal transformer  with a very low  radiated magnetic field and high efficiency is an excellent choice for audio and other sensitive devices. 

In our stable stock offer can be from now found a quality small transformer 70053K from company Talema meeting even high requirements for supplying of sensitive devices. Switch mode power supplies are an excellent choice for the most of applications, but for supplying of input stages of audio and video devices as well as various measuring devices, AD converters, … it´s still the best choice a classic transformer. And if it has to be a transformer, then the one with as good specification as possible.

From this point of view, toroidal transformers a are a step in front of transformers laminated from EI, C and similar plates. A uniform layout of primary and secondary winding along the magnetic core of the toroid ensures an excellent magnetic coupling between windings a very low strayfield, which could influence surrounded components in a device.

Transformers from company Talema are top quality products meeting stringent requirements for safety, reliability and low losses.  Type 70053K with the 2x15V output (2×18,5V open circuit) is ideal for supplying of audio and other devices requiring +-15V symmetrical voltage. At lower current demands, it is also suitable for +-18V output, as an AC voltage will get increased after rectification and filtering at capacitors.
The transformer has a double primary winding, thus being able to operate at 115 or 230V (i.e. in European conditions the windings have to be connected in series). A big advantage is that secondary windings are separated, and so they can be connected even in parallel in order to gain a higher current in cases when we only need a single supply. Application of the transformer is very simple – by soldering pins into a PCB. The transformer also features a blind plastic nut M4x6 for increasing of mechanical stability.

Detailed information can be found in the Talema 70000 datasheet as well as in the series  70000 overview.  In case of interest, please contact us at info@soselectronic.com.

If you need an isolated power supply for some part of your device, Traco TMH series DC/DC converters will create this second voltage to you. 

Imagine, that in the whole device we only have 5 Volts but for one integrated we need a higher voltage. Or we even have a suitable voltage, but for a protection of input voltages, suppression of disturbances etc. we need an isolated power supply for a given part of our device …

For such cases we keep in our standard stock offer many isolating DC/DC converters from company Traco Electronic, but we´d like to introduce to you miniature “retiring” 2W DC/DC converters of the TMH series with an excellent price/ performance ratio. It can be said, that the TMH series represents a golden middle way as for specification, efficiency, dimensions and price. Reliable regulation within 10% at 20-100% load, miniature SIP package and a wide temperature range of -40 to +85°C suit to the most of applications. Available are versions with a single (S) but also dual (D) output voltage.

TMH series is very useful in places, where it is necessary to use isolated power supply, but in regards to its affordable price and miniature dimensions is the TMH series suitable even in places, where an isolated power supply is not inevitably necessary but it can help to increase immunity to disturbances, ground loops and other unexpected influences, which can occur. A big advantage of the TMH series is the 100% 8h burn-in. A novelty in our stock is the type TMH0515S 5VDC/15VDC. Detailed information can be found in the TMH datasheet.

The new iW3606 and iW3608 single-stage, solid state lighting (SSL) LED drivers from iWatt feature a wide, flicker-free dimming range from 100% all the way down to 1% of measured light, to closely match the dimming performance of incandescent bulbs. This enables the smooth, “natural” dimming, with no light drop-out at the low end of the dimming range and virtually no dead travel where the light turns off before the dimmer control reaches the bottom of its travel. The very low internal power consumption of the iW3606 and iW3608 allows them to start at a very low dimming level of <5% of light output. This virtually eliminates pop-on, a phenomenon where the light does not turn on at low dimmer levels and as the dimmer level is raised, the light suddenly turns on. This also helps eliminate popcorning effects, in which various bulbs in multiple-light installations on the same dimmer circuit can turn on at different dimmer setting thresholds. [via]
