Evolving Ef f iciency StandardsEvolving regulations and incentives, targeted towards improving energy efficiency, are intended to limit global climate change. Enhancing power supply efficiency alone can save over 2% of global energy consumption. Many organizations worldwide (such as China Certification Center, USA Environmental Protection Agency, European Code of Conduct) now develop regulations and incentives for power supply efficiency, like ENERGY STAR® and 80 PLUS®. ON Semiconductor actively participates in standards organizations and working groups, so that we can provide solutions to the market that meet all of the relevant specifications, worldwide.

Power Supply E xper tiseON Semiconductor provides products and solutions that save power From the Socket to the Pocket™, enabling quick deployment of cost-effective power supplies that meet evolving global efficiency standards. Our expertise in high-efficiency power supplies helps solve your challenges in all focus areas for efficiency enhancement:

• Low standby-mode power consumption

• High active-mode power efficiency

• Power factor correction

And since we provide a full range of power supply semiconductors – from highly integrated power factor controllers, ac-dc controllers, and dc-dc controllers, to discrete MOSFETs, rectifiers, diodes, and transistors – we can help you design complete power supply solutions, with all active components sourced from and supported by a single supplier.

GreenPoint® Reference DesignsON Semiconductor provides GreenPoint reference designs for selected types of internal and external power supplies. These open reference designs provide roadmaps for the design of highly efficient power supplies, helping you get to market quickly by providing documentation that includes schematics, BOMs, Gerber files, design descriptions, and test results. The reference designs meet all relevant global efficiency standards, providing access to global markets with a single design.

Global Power Supply PresenceON Semiconductor maintains a broad, global network of design and applications resources, including resources devoted to power supplies.

Our Product Design Centers define and develop advanced power management integrated circuits, utilizing the latest architectures and development tools. Products are targeted for a range of process technologies, including analog CMOS, Bi-CMOS, and Very High Voltage (VHV).

Our Solutions Engineering Centers focus on developing value-added total solutions for specific end market applications. These centers are staffed with applications engineers with design experience, and are equipped with all of the resources necessary for local manufacturers to benefit from the vast power management experience of ON Semiconductor.

A global network of Field Applications Engineers provides truly customer-specific support. These local resources can help you optimize your power supply designs, by contributing their experience and training, with both applications and specific components, to your design location.
