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.
