Allegro Introduces New Offline PWM Switching Regulator IC Family
Allegro MicroSystems Inc. introduces the STR2W100 and STR3A100 power IC series designed for switching power supplies. These new devices incorporate a power MOSFET and a current mode PWM controller IC in one package. Each package includes a startup circuit and a standby function in the controller, which achieves low power consumption, low standby power, and high cost-effectiveness in power supply systems, while reducing external components.

These devices are offered by Allegro and manufacture and developed by Sanken Electric Co., Ltd. in Japan. This new series is targeted at the consumer, industrial and office automation markets with end applications to include set top boxes, home and digital appliances, office automation equipment and industrial apparatus. Improved internal circuitry can achieve significant reductions in no-load power consumption, up to 10 mW in the STR3A100 series and up to 25 mW in the STR2W100 series.
Two package options are available. The STR2W100 is available in the TO-220F-6L package and the STR3A100 is available in the DIP-8 package.

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.
