Power Integrations Introduces 75W Single-Stage Driver for LED Lighting
Power Integrations announced two new additions to its LinkSwitch™PH IC family. The new devices allow commercial lighting applications up to 75W to benefit from single-stage design, dramatically reducing BOM cost and enabling a smaller driver with very high efficiency.
LNK410EG (dimming) and LNK420EG (non-dimming) provide a constant-current output with a PF- corrected and low THD input. The capabilities of the new devices are showcased in RDR-290, a reference design describing a single-output driver for high-bay lighting.
RDR-290 is 92.2% efficient at 230Vac for a 75W output design while easily meeting EN61000-3-2 class C limits. Power factor is above 0.95. No primary high-voltage electrolytic bulk capacitor is required, making lifetimes of 50,000 hours practical, even in challenging outdoor environments and at high ambient temperatures.
Comments Andrew Smith, product marketing manager at Power Integrations, "By greatly increasing the power capability of single-stage conversion, the efficiency and longevity benefits of the single-stage approach can now be applied to industrial and commercial LED lighting – the market that most needs those characteristics."

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.
