90 watt power adapter Semiconductor meet European standards for laptop computers

ON Semiconductor (ON Semiconductor) announced Disi Kuan GreenPoint reference design for the 90 watt laptop power adapter. The reference design uses a single-stage method, eliminating the burden of dealing with two power supply adapter to resolve all power modules at the same time, access to low standby power consumption, and MC145051DW datasheet and in accordance with the California Energy Commission (CEC), Energy Star and MC145051DW price and the European act Standards (Code of Conduct) requirements. GreenPoint adapter reference design of new energy efficiency of 90%. The design uses a patented single-stage topology, the need far fewer components than traditional two-stage program. The reference design meets OEM on the surface temperature and MC145051DW suppliers and 100 microamps (μA) the following leakage current requirements. According to reports, to reduce output ripple and maintain harmonic currents in the IEC1000-3-2 Class D requirements specified in the reference design uses Energy Recovery Systems Corporation developed the double-loop ripple / power factor optimization techniques The company is the ON Semiconductor in this innovative adapter reference design technology and product development partners.

NCP1651 is the dominant device in the reference design. The device is designed for 50/60Hz universal input power supply system in the range (85Vac-265Vac) active power factor correction controller. It is the high output voltage requirements of the isolated DC-DC converter provides a low cost, component count solution and easily meet the range of 50W-250W converter IEC1000-3-2 harmonic requirements. NCP1651 uses a proprietary multiplier design, compared with traditional analog multiplier, the operation more precise. The device SOIC-16 package and is priced per 2,500 1.82 U.S. dollars. Other supportive devices, including programmable precision reference TL431, single-supply dual operational amplifier LM358, low offset voltage dual comparator LM393, and 20A, 100V H Series Schottky Rectifier MBR20H100. Adapter reference design complete documentation including description, block diagram, specifications and evaluation results. ON Semiconductor introduced, the company has with the Energy Recovery Systems Corporation (ERS) established a formal relationship, choose the ERS and to calculate the field of power as an adapter power system design and develop the project partners, are focused primarily in the power supply design of the ERS expertise. ERS President Abdul Sher-Jan, said: "With patented design, we can overcome the shortcomings of single-stage topology, and directly address the specific requirements of notebook power adapter. We work with ON Semiconductor has developed a low-cost single-stage solution can not only provide the required performance and design complexity much lower than the more complex and more commonly used two programs.
