Toshiba Launches High-speed Dual N-channel MOSFETs

Toshiba Corporation has launched a low-capacitance, 4A dual N-channel MOSFET for high-speed switches in the high-current charging circuits of mobile devices, such as smartphones and tablets. Operating at 3MHz, these devices feature a typical on-resistance of 67 mOhms with a V(GS) of 4.5V and are packaged in a 2mm square SOT1118 configuration. QG is is 1.8 nC, VGSS is +/-12V and VDSS is 30V

As additional functions are added to mobile devices, including smartphones, cellular phones, tablets and notebook PCs, and as increasing demands are made on the batteries of those devices, efforts continue to improve the user experience and cut charge times by boosting charge density and significantly increasing the charging current and frequency. Toshiba's new low capacitance product "SSM6N58NU" is the company's latest addition to its dual N-channel MOSFET line-up, suitable as high-speed switches for high-current charging circuits.

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.
