The DX3522 is a highly integrated with the highpower factor correction controller for non-isolatedBUCK , BUCK BOOST,BOOST configurationapplication,it uses advanced algorithm to detect thedimmer phase angle and dim the LED outputcurrent accordingly.The DX3522 can be operated in DiscontinuousConducted Mode(DCM) and Slightly Continuous

Conducted Mode(SCCM) to get ease EMIdesigning and good dimmer compatibility.The DX3522 build-in high voltage MOSFET andfew of external components,DX3522 is suitable forcompact and cost-effective dimmable systemdesign.
