Oak Ridge Studies Effect Of Hybrids On Power Demands
Some people wonder whether an increasing number of plug-in hybrid electric cars and trucks will require major new power-generation resources. A study by the Oak Ridge National Laboratory provides a definitive answer: maybe. The study, published in the current issue of the ORNL Review, said the answer depends on when people recharge their cars.

RF Power Detector Simplifies Power Measurement And Control
Intel, NEC Team Up To Develop PMIC For Mobile Web Devices
Intel and NEC Electronics America have teamed up to develop a power-management IC (PMIC) solution optimized for mobile Internet devices (MIDs), with initial samples available in the third quarter. The partnership leads to some questions that boil down to what power management has to do with Intel, and why Intel chose NEC for this project.
Tiny Synchronous Step-Up Converter Starts Up at 700 mV
Alkaline batteries are convenient because they’re easy to find and relatively inexpensive, making them the power source of choice for portable instruments and devices used for outdoor recreation.
Boost Data-Center Performance While Lowering Cost And Power Consumption
6-Channel SAR ADCs for Industrial Monitoring and Portable
The 14-bit LTC2351-14 is a 1.5 Msps, low-power SAR ADC with six simultaneously sampled differential input channels. It operates from a single 3-V supply and features six independent sample-and-hold amplifiers and a single ADC. The single ADC with multiple S/HAs enables excellent range match (1 mV) between channels and channel-to-channel skew (200 ps).
High Power PoE PD Interface With Integrated Flyback Controller
To this day, Power over Ethernet (PoE) continues to gain popularity in today’s networking world. The 12.95 W delivered to the powered device (PD) input supplied by the Power Sourcing Equipment (PSE) is a universal supply. Each PD provides its own dc-dc conversion from a nominal 48-V supply, thus eliminating the need for a correct-voltage wall adapter.
Buck-Boost Controller Simplifies Design Of DC-DC Converters For Handheld Products
A number of conventional solutions have been available for the design of a DC/DC converter where the output voltage is within the input voltage range—a common scenario
in Li-Ion battery-powered applications—but none were very attractive until now.
Dual Op Amp Draws 20 µA Per Unit
Designed for portable applications requiring high accuracy, the AD8506 low-power dual CMOS operational amplifier from Analog Devices Inc. consumes only 20 µA per amplifier. The device, with rail-to-rail inputs and output, is designed for use in battery-powered patient monitors, remote sensors, handheld instrumentation, and other mobile equipment that requires precision measurement at low voltages.
Dual-Output Step-Down Converters Feature Low Capacitance
A family of four dual-output dc-dc step-down converters with integrated FETs deliver 2-A and 3-A continuous output current and accommodate input voltages from 4.5 to 28 V. Texas Instruments’ 2-A TPS54283 (300-kHz switching frequency), TPS54286 (600 kHz), 3-A TPS54383 (300 kHz), and TPS54386 (600 kHz) Swift converters reduce input-capacitance by switching each output at 180º out-of-phase.
ON Semiconductor Spends $185 Mil. Cash For ADI Thermal, Voltage Products
ON Semiconductor Corporation has signed an agreement with Analog Devices Inc. to acquire voltage regulation and thermal monitoring products for computing applications. ON Semiconductor will acquire assets and intellectual property related to these monitoring and regulatory technologies, and will hold a manufacturing supply arrangement with Analog Devices over the next year for a total approximately $185 million.
Ultraprecise Current Sense Amplifier Dramatically Enhances Efficiency and Dynamic Range
Accurate current measurement is indispensable in many electronic systems. The current is usually measured by amplifying the voltage it generates across a small value resistance.
Hot-Swap Protection IC Requires No External Sense Resistor
Allegro Microsystems’ ACS760 employs the company’s Hall-effect current-sensing technology to implement three levels of fault protection. The ACS760 hot-swap protection IC from Allegro Microsystems Inc. combines the company’s Hall-effect current-sensing technology with hot-swap control circuitry to create a highly efficient integrated controller for 12-V hot-swap applications...

LDOs Feature Small Size, Low Quiescent Current
Catalyst Semiconductor's CAT6217 (150 mA) and CAT6218 (300 mA) low-dropout regulators suit low-noise, low-power applications.
Going Green – A Light in the Dark
The European Union’s RoHS (Restriction of Hazardous Substances) Directive came into force a year ago. This directive bans new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants.
Load Switches Cover Range Of Input Voltages, Currents
Fairchild Semiconductor's FPX250X series of load switches, part of its IntelliMAX product line, handles inputs of 4.5 to 20 V and current limits of 0.4 to 2 A, while integrating several protection features.
