DX3522 TRIAC dimmable,Non-isolated Offline LED Controller DESCRIPTION PIN ASSIGNMENTS The DX3522 is a highly integrated with the high SOIC-7 power factor correction controller for non-isolated KONGSON BUCK , BUCK BOOST,BOOST configuration application,it uses advanced algorithm to detect the dimmer phase angle and dim the LED output current accordingly. The DX3522 can be operated in Discontinuous Conducted Mode(DCM) and Slightly Continuous Conducted Mode(SCCM) to get ease EMI designing and good dimmer compatibility. The DX3522 build-in high voltage MOSFET and few of external components,DX3522 is suitable for compact and cost-effective dimmable system design.
