ON Semiconductor Introduces High Efficiency Wireless Charging ICs
ON Semiconductor has released the NMLU1210, an innovative power MOSFET integrated circuit (IC) for wireless charging applications in portable products such as cell phones, media tablets, portable media players, digital still cameras and GPS units.
The NMLU1210 is a 20V N-channel full bridge semi-synchronous rectifier, that incorporates a dual Schottky barrier diode supporting up to 3.2A operation plus two MOSFETs with a 17mΩ (ma") (typical) Rds(ON) to minimize conduction losses and substantially increase efficiency of the charging system.
Wireless inductive charging is becoming increasingly popular, freeing consumers from the inconvenience of the traditional wired approach. It works on the principle of an electromagnetic field being created for the rapid transfer of energy between the transmitter (in the charging station) and the receiver (in the portable device). The NMLU1210 is used by the receiver side to convert ac voltage generated by the transmitter to dc voltage used for battery charging. Offered in an ultra-low inductance thermally efficient package, it is optimized specifically for power management tasks in portable electronic products. This compact IC is highly suited to use in space-constrained environments. It has an operational junction temperature of --55 to 125°C.

"The NMLU1210 full bridge rectifier enables more efficient and faster wireless charging of portable electronics devices," said Paul Leonard, vice president of ON Semiconductor’s Power MOSFET products division. "This innovative device will enable OEMs to offer their customers more flexibility in battery recharging which will give their products improved power features in an increasingly competitive consumer space."
"ON Semiconductor is an important member of the Wireless Power Consortium," said Menno Treffers, chairman of the Wireless Power Consortium. "The addition of NMLU1210 to ON Semiconductor’s extensive product portfolio gives the industry more choice and makes it possible to apply the Qi wireless power standard in far more applications and products."
Opinion: Maximising Synergies between Power Electronics and ICT for improving Energy Efficiency
The NMLU1210 is offered in a 4.0 x 4.0 x 0.5mm uCool, RoHS-compliant package. The device is priced at $0.70 per unit in 10,000 unit quantities.

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.
