Hiper PFS range for small PFC 100-265VAC, 400W
I have offered to do a HiperPFS PFC for a company at 400W, 100-265VAC. (followed by an LLC) 37Vout.
Its for a consumer beauty product
But they believe a totem pole PFC stage will be a smaller and more efficient solution.
They want a really small solution as the customer may have to carry it on holiday etc.
Would you agree?
Thanks, regarding PFC at 400W...do you believe that Totem pole PFC is more efficient then hiperPFS?.. or does the totem pole controller micro have a few watts of bias power, and so its not worth doing totem pole at 200-400W?
A comparison between HiperPFS-5 with a totem pole solution at 200-400W can not be made.
HiperPFS-5 can only deliver 240W of continuous power which is essentially the minimum power you are referring to.
Power Integrations does not have a totem pole solution that can be compared with HiperPFS-4 at 240W either.
Thank you for showing interest in Power Integrations' products.
HiperPFS-5 can only deliver up to 240W of continuous power at 90VAC.
It will not be sufficient for your power requirement of 400W.
Please refer to the HiperPFS-5 datasheet for more information.
