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.

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]

STMicroelectronics has introduced its latest generation of energy-efficient power devices that reduce the environmental impact of equipment such as telecom or computing systems, solar inverters, industrial automation and automotive applications. The new STripFET VII DeepGATE MOSFETs deliver the best conducting efficiency among currently available 80V and 100V devices, while switching efficiency is also increased.
The critical advance in the new technology is an enhanced MOSFET gate structure, which lowers device on-state resistance while also reducing internal capacitances and gate charge for faster, more efficient switching. The devices also have high avalanche ruggedness to survive potentially damaging hard conditions, which makes them a strong choice for automotive applications.

Touchstone, with its first analog power management product, has enhanced such a function with the capability to use supply voltages down to 0.6V while still being able to deliver a 75 mA output current.
The device can be used in power harvesting or peak load buffering applications, the LDO may post-regulate voltage buffered in a large capacitor or super-capacitor at boost’s output. Finally, the LDO may be operated simply as an on/off load switch.
