DESCRIPTION PIN ASSIGNMENTSThe DX3580 is a high performance, single-stagepower factor (PF) corrected AC/DC controllerdesigned for off-line TRIAC dimmable LED lightingapplications.The DX3580 adopts high precise LED

current controlling that it is intended fornon-isolated Buck and Buck-Boost applications.The DX3580 implements a unique LED currentcontrolling algorithm to maintain accurate outputcurrent regulation.The DX3580 operates in

Boundary Conduction Mode(BCM) with the valleyswitching and power factor correction features toget easy Electromagnetic Interference(EMI) andlow total harmonic distortion.
