Intersil's ISL6446A Dual PWM/Linear Controller Provides Efficient, Flexible Single-Chip Solution
Intersil Corporation has introduced a new dual PWM + linear controller that delivers the industry’s most flexible, efficient power solution for a broad variety of broadband and networking applications. The ISL6446A integrates complete control, monitoring and protection functions for two synchronous buck PWM controllers and one linear controller. It allows designers to easily convert 4.5V to 24V dc into as many as three output voltages, with extensive protection. Each output can be controlled independently with adjustable soft-start control.

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.
