Designing world-class power supplies is getting harder. Every year, your customers demand more power from a smaller space at a lower cost. In addition, new regulations are imposing increasingly stringent requirements on power conversion efficiency, quality, and standby consumption. ON Semiconductor provides a diverse portfolio of power management solutions to meet the needs of designers worldwide. Our products help you produce more power in a smaller footprint while meeting power consumption specifications such as Energy Star® and Blue Angel*, and PFC requirements such as IEC1000-3-2. ON Semiconductor covers the complete power chain, from industrial power supplies to consumer applications such as DVD players, set top boxes, computers, laptops and cell phones. For two consecutive years, ON Semiconductor has been the only chip manufacturer recognized by the China Cer t i f ication Center for Energy Conservation Products (CECP) to support China's drive for standby power reduction and energy conservation. We are participating in European Commission (EC) work groups developing a Code of Conduct to help reduce standby losses in a wide range of consumer equipment. WW inning Feature Setsinning Feature Sets ON Semiconductor offers a wide variety of controllers with features to fit your application: �� Fixed frequency current or voltage mode topologies �� Variable-frequency Quasi-Resonant (QR) architectures for higher efficiency and better EMI �� Skip cycle or frequency foldback circuits for excellent standby performance �� Fixed on-time/variable off-time switching for low power applications �� Hysteretic-type control for ease of implementation �� Comprehensive protection and safety options Reach the Minimum.Reach the Minimum. .. .. Complying with exist ing and future energy conversion regulations can be challenging. Power controllers and switching regulators from ON Semi- conductor minimize standby power consumption and maximize power conversion efficiency. For example, a 70 W power supply reference design built with the NCP1203 has been shown to consume only 86 mW at no-load conditions — the best performance in its class.
