O2Micro Introduces LED Driver Controller for Single-SKU, Global LED Bulbs
O2Micro International Limited extended its general lighting product portfolio with the introduction of the OZ8022VM LED driver controller. The OZ8022VM is designed to address the high-volume, non-dimming incandescent bulb replacement market, which includes PAR lamps, A bulbs and BR bulbs.

The OZ8022VM supports universal 85Vac to 265Vac operation, enabling a single LED bulb to address the global marketplace, reducing SKUs and increasing operational efficiencies resulting from economy of scale. LED current regulation and accuracy over the entire universal input range ensures consistent lumen output globally, regardless of varying line input conditions.
The OZ8022VM features a built-in, high-voltage power MOSFET in a cost-effective, small footprint, 8-pin SOP package. The high integration enables a low BOM count and resulting low cost at the system BOM level, as well as compact design, accommodating space-constrained applications.

Integrated power factor correction ensures high power factor (>0.9 over the universal 85-265Vac input range) and low THD ( <20%), enabling bulbs that incorporate the OZ8022VM to meet worldwide residential and commercial requirements and regulations, such as EPA Energy Star. Efficiency of greater than 88% is maintained across the entire universal voltage range, reducing energy consumption and simplifying thermal management. During light-load conditions, minimum off-time control maximizes operating efficiency. Low start-up current and operation current also maximize conversion efficiency.
The OZ8022VM is designed for non-isolated buck converter applications, utilizing quasi-resonant conversion technology. The OZ8022VM features fast turn-on to meet end-user expectations. Integrated over-temperature, over-voltage, cycle-by-cycle current limiting, LED open circuit and LED short circuit protection, with auto-recovery, provide safe and reliable operation.

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.
