Hi,
We are thinking of buying this SmartEgg charger for 140W offline 90-265VAC
It is actually a version of the following, shown on Fig 5, page 9...
One obviously needs to just use a micro so as to keep the volt seconds from flying off either positively or negatively.
Seems strange there aren't OTS chip solutions for it? (or are there some?), since it is just a version of the well known PFC bias supply as shown above.
You can see that the Boost PFC has been made synchronous.
