QI'm currently working on the design of a 100W dimmable LED driver, and am in
need of a controller chip with combined PFC controller and switching control.
The LED driver needs to dim down to less than 1%, and comply with IEC61000-3-2
class C harmonics requirements.
Assistance in choosing an appropriate switching controller is much appreciated.
AUnfortunately we do not have a complete AC/DC type solution including PFC
available. However, you might be interested in our ADP8140 as a solution to
convert any voltage power source into a current source to drive LEDs. I have
included a screenshot of a typical application.
