TI Introduces Flexible PFET High-side Load Switch with Level Shift and Slew-rate Control
Texas Instruments Incorporated introduced a high-side load switch that integrates a power PFET and a control NFET in a tiny 6-pin package. Offering support for the industry's widest supply voltage range at 1.0 V up to 8 V, the TPS27081A is the most flexible replacement for discrete FET switches. The load switch also offers adjustable slew-rate control so designers can implement the device in any application that requires load switching or power sequencing, including notebooks, tablets, LCD televisions, global positioning systems (GPS) and set-top boxes.
Key features and benefits
* Better flexibility: Higher voltage range of operation for both the on/off function and input/output voltages supports wider range of applications with lower bill-of-materials cost.

* Higher reliability in the system: Supply inputs are fully protected against ESD strikes on all pins, thus providing better ESD compatibility with other on-board components than the competition.
* Ensures high efficiency: Low ON resistance with the high-current PFET ensures low voltage drop across the PMOS transistor.
* Higher Reliability: High-pulsed current rating allows reliability under short-circuit conditions, which ensures longer product lifetimes.
* Broad power switch portfolio: The TPS27081A complements TI's low ON-resistance integrated load switches, such as the TPS22965 and the TPS22929D.
The TPS27081A is available in a 2.9-mm x 1.6-mm x 0.75-mm thin SOT-23 (DDC) package. Suggested retail pricing in 1000-unit quantities is US$0.12.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
