Yep, on a simelar subject it seems they will entirely remove the quasi- peak detector and use only peak detector for emission measurements - so all dirty tricks like spreadspectrum modulation techniques is no use in the future

Very nice idea indeed :-)

Perhaps you'd have a more realistic product if you split the design function between two converters in the same style of package - perhaps the only internal difference would be the front end electronics. This is a fairly common method of dealing with extended voltage ranges and it makes sense.

Although it would be nice to claim such a wide compliance, it will mean multiple input circuits that rely on the integrity of housekeeping monitors or inrush limiters to connect them suitably. This a complication and a cost that is probably not currently justified by commercial demand, even at this relatively low power level.

Customers damanding the performance, without also being prepared to shoulder the financial impact, are best avoided. Designers claiming to have beaten both should feel free to market the results, without disclosure on usenet and without any advice from me.
