Linear Technology has introduced the LTC4089 and LTC4089-5, each featuring an autonomous power manager, ideal diode controller and standalone high-voltage switching battery charger for portable USB devices. For high efficiency charging, their switching topology accommodates various inputs, including high voltage power sources up to 36V (40V max) such as 12V AC-DC wall adapters, FireWire ports or automotive batteries. In addition, they accept low-...

Vicor has released its 1RU, high power density PFC FrontEnd for use with various power modules. The ultra-low profile, fan-cooled, power factor corrected AC-DC front end operates from a wide range 85-264Vac input, providing 375V out with a power density of over 28W/in3.

Vicor has announced the availability of a full family of V•I ChipTM components, enabling complete power systems using Factorized Power Architecture (FPA). FPA separates or ‘factorizes’ regulation and voltage transformation functions into flexible, high-performance building blocks. V•I Chip components are high-density (up to 1.2kW/in3), high-efficiency (up to 97%), high-speed power conversion modules, and are all released for mass product...

The 28Vdc MIL-COTS VIPAC family of power systems is a new class of user-defined, modular power solutions for military COTS applications such as radar, military ground vehicle, communications equipment, and aerospace. It incorporates Vicor’s M-FIAM5B, which provides MIL-STD-461E EMI filtering and MIL-STD-704E/F transient protection; Vicor's Maxi, Mini and Micro DC-DC H or M grade converters; and a choice of output connections and mechanical plat...

Texas Instruments has introduced what it says is the smalles the smallest two-bank, low dropout (LDO) regulator to support light emitting diode (LED) lighting in portable applications, such as mobile phones, navigation systems, MP3 and media players. The device enables quality color backlighting from a tiny 1.2 mm x 1.2 mm package, allowing end-users to experience blinking and dimming of color keypads and navigation pad lights.

SEMIKRON has introduced its SEMiSTART family of anti-parallel uninsulated thyristor modules, which has been designed specifically for use in soft-start devices. The modules are extremely compact. For example, a 400kW soft-starter featuring SEMiSTART is only one-sixth of the volume of the same device using conventional capsule thyristors. In addition, by using pressure contact technology and double-sided chip cooling, these new modules can withsta...

XP Power announces the latest model in the fleXPower family of configurable power supplies. The fleXPower X10 brings an 11% increase in power using the same size chassis as earlier 900 Watt models. An output power of up to 1,000 Watts is available over the full input range of 85-264 VAC. At high line, 180-264 VAC, a single chassis can provide up to 1,200 Watts. By utilising the double deck feature of the fleXPower X10, where outputs are parallele...

The A8530 from Allegro MicroSystems Europe is a high-efficiency charge pump integrated circuit that offers a simple, low-cost white LED driver solution for driving four display backlight and two flash/torch video-mode white LEDs.

Schaefer, Inc., a market leader of power electronics, announces their application specific solutions for supplying the distinct power needs of the photonics industry, including laser and high pressure mercury lamp requirements. Photonics applications typically require the power supply to provide extremely stable voltages under diverse conditions, significant surge ratings during start-up cycles and controlled energy storage.

AnalogicTech has introduced the AAT2550, a highly integrated power management IC for smart phones, portable media/music players, and other handheld computing devices. Targeted at portable systems powered by single-cell lithium ion/polymer batteries rated up to 1500mAh, the highly integrated device saves PCB space by combining a 1A battery charger with two 600mA step-down converters in a small 4 x 4mm QFN package.
