Silicon Laboratories has announced the industry’s first dual-function, single-port Power over Ethernet (PoE) controller with an integrated DC/DC controller for power sourcing equipment (PSE). By combining these two functions, the Si3460 simplifies development efforts, reduces system costs and eliminates specification compliance challenges for designers of a broad range of emerging PoE applications such as in home gateways, set-top boxes, cable ...

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.

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...

Linear Technology has announced the LTC3555, the first in a family of next generation multi-function power management solutions for Li-Ion/Polymer battery applications. The LTC3555 integrates a switching PowerPath manager, a standalone battery charger, an ideal diode, I2C control, three high efficiency synchronous buck regulators plus an always-on LDO, all in a compact, low-profile 4mm x 5mm QFN package. The LTC3555's PowerPath control feature ...

AnalogicTech has introduced the AAT4282A, a dual, slew rate controlled load switch that allows designers to reduce parts count and cost by integrating two low resistance slew rate controlled load switches in a single 2 x 2mm package. Part of AnalogicTech’s rapidly growing application specific Power MOSFET (ASPM) product family, the AAT4282A features two MOSFETs, each with a typical RDS(ON) of just 60mohms at 5V to support higher load switch cur...
