Linear Technology has announced the LTC3557, a multi-function power management solution for Li-Ion/Polymer battery applications. The LTC3557 integrates a linear PowerPath manager, a standalone battery charger, ideal diode, three high efficiency synchronous buck regulators and an always-on LDO in a low-profile 4mm x 4mm QFN package. The powerpath manager seamlessly manages the transition between multiple input sources and power to the load, while ...

Leading power solutions specialist Powersolve announces the TRACOPOWER THN-15 series of high performance DC/DC converter modules. They provide up to 15W output power from an encapsulated, shielded metal package with dimensions of only 1.0x1.0x 0.4in. According to Powersolve’s Managing Director Peter Clark, the THN-15 series sets a new benchmark for isolated 15W converters.

METcase has published their new 2007 Aluminium Enclosures Catalogue which details their comprehensive range of desktop, portable, wall mounting and 19in enclosures. This 28 page colour catalogue provides design engineers with an invaluable selection of modern, versatile and cost effective aluminium housings. The ordering information, drawings, material specifications and customising options are all set out in a clear and easy to use format.

Molex has introduced Sealed SFP Assemblies in response to customer demands to incorporate SFP transceivers into sealed panel mounted receptacles. These new solutions also meet a market need for upgrades from a copper Ethernet system to an optical transceiver, or can interchange between the two as requirements demand.

Tyco Electronics has announced an addition to its PolySwitch resettable PPTC (polymeric positive temperature coefficient) devices surface-mount product family. Useful for the latest generation of high frequency data ports, I/O ports and storage devices, the picoSMD035F device offers circuit designers the smallest PPTC overcurrent protection device available for consumer and computer electronics.

Fairchild Semiconductor highly integrated Green FPS power switch, the FSFR2100 , increases power efficiency and system reliability, and reduces valuable design time in resonant converter designs such as telecom power, high end audio amplifiers, large size laser printers and LCD and PDP TV power supplies. Offering a “system-in-a-package” approach that integrates everything necessary to build reliable and efficient resonant converters, this pow...

The Power Sources Manufacturers Association PSMA announces that it has undertaken a Special Project to survey the Power Supply in Package (PSiP) and Power Supply on Chip (PSoC) landscape and to provide insight to both PSMA members and the broader industry as to the potential impact of this paradigm shift within the power industry.

The new A4931 from Allegro MicroSystems Europe is a 3-phase brushless DC motor pre-driver integrated circuit with outputs for the direct high-current gate drive of an all N-channel power MOSFET 3-phase bridge with a maximum supply voltage of 38 V. The device includes three Hall-element inputs, a sequencer for commutation control, fixed off-time pulse width modulation (PWM) current control and locked rotor protection. Output current is scalable w...

Power-One has introduced three 65W, single-output, AC/DC power supplies delivering 15, 24, and 48VDC; the SBLP65-1015G, SBLP65-1024G, and SBLP65-1048G. A quasi-resonant zero-voltage switching topology delivers efficiencies of 80 – 85% at full-power operation and at load conditions as low as 10%; providing significant energy savings in networking, commercial, and industrial applications.

Texas Instruments has introduced four dual-output SWIFT DC/DC step-down converters with integrated FETs that deliver 2 A and 3 A of continuous output current and support input voltages of 4.5 V to 28 V. The simple-to-design switchers, which come in a monolithic package, speed time to market, reduce external component count and help reduce cost for point-of-load systems used in a wide variety of applications including HDTVs, set-top boxes and othe...
