How to improve the power factor about the device ncl30001?What's the matter with my ncl30001,Pf=0.7,when vin=220VAC?

Please let me know:\n What is the load - Vout and Iout?\n What type of equipment are you using to measure power factor?\n\nIf you can provide a schematic of your own prototype we can give you some feedback, inherently this architecture will provide very good power factor but the EMI filter can impact that. See Tip 6 in AND8462 which discusses the impact of the EMI filter on PF performance. Here is our contact at: http://www.onsemi.com/PowerSolutions/ticrequest.do Thank you. Answered by:
