Power-One has introduced the Aurora PVI-6000 Series of photovoltaic and wind inverters. These grid-tie products utilize two high-speed, independent MPPT (Max Power Point Tracking) channels to optimize energy harvesting in installations with multiple PV arrays oriented in different directions. The amount of available energy is also increased through the use of transformerless designs that provide up to 97% (96.5% C.E.C) conversion efficiencies.

Bringing higher power to its PKJ 4000 series of DC/DC converters, Ericsson Power Modules’ PKJ 4316 API is rated at 350W. The fully featured converter offers designers high quality and a cost-effective solution for demanding radio frequency power amplifier (RFPA) applications.

Semtech has announced the SC2447, said to be the industry’s first DC-DC step-down (buck) controller for DrMOS power devices. The SC2447 is a 1MHz synchronous PWM buck controller designed to drive DrMOS power devices in compact, high-efficiency DC-DC power converters for telecom, datacom, switches, routers, and other high-end applications. The dual-channel SC2447 can produce two independent outputs of up to 30A each or a single high-current out...

Powersolve announces a range of Class ll (no earth) desk-top power supplies for applications requiring high isolation and are ideal for powering LCD monitors, notebooks, printers and modems. They are housed in a compact 103 x 45 x 36mm enclosure with a 2.5 x 5.5 x 9.5 barrel output connector as standard.

XP Power has announced availability of the SDS150, a compact, high density, convection cooled power supply that is ideally suited to IT and industrial applications where space is at a premium and there are no internal fans. Both open frame and U channel models can be used in 1U customer applications. The open frame model, 76 x 127 x 36 mm (3 x 5 x 1.44 inches), offers the highest power density of 6.9 watts per cubic inch and the U channel, 81 x 1...

Texas Instruments has introduced a family of ORing power controllers with advanced features and high performance that improves power distribution in 12-V blade servers, N+1 telecom systems and redundant low-voltage processor power supplies. The integrated circuits provide a high-efficiency replacement for ORing diodes, and offer intelligent monitoring and control of power supplies to prevent bus transient events from causing board-damaging faults...

Linear Technology has introduced the LTC3822, a 2.75V to 4.5V input synchronous step-down DC/DC controller that drives N-channel MOSFETs without requiring an external supply for gate drive. In addition, the LTC3822 eliminates the need for a sense resistor by using MOSFET RDS(ON) sensing current, which improves efficiency and reduces solution cost.

Power Integrations has announced that all members of its LinkSwitch TN, -LP and -XT families of ICs are now available in SO-8 packaging, enabling emerging applications such as LED lightbulbs and miniature chargers.

Power Integrations has introduced a reference design kit (RDK-131) for ultra-small power supplies that helps designers deliver energy-efficient LED alternatives to incandescent lights. The kit helps designers produce a power circuit that fits inside the LED lightbulb socket, and also ensure that their incandescent-replacement LED lightbulbs will pass EMC requirements for conducted and radiated electrical noise.

Vicor Corporation announces the addition of nine mid-power Mini DC-DC converters to the 24Vdc input family: a 100W model at 3.3Vout, 150W models at 5, 12, 15, 24, 28, 36, and 48Vout. A 200W model at a new standard 36V output has also been added. The modules — which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) — can be used as a cost-effective option in a variety of applications, including industri...
