High Performance,TRIAC dimmable, Non-isolated Offline LED Controller
產(chǎn)品描述
The DX3580 is a high performance, single-stage powerfactor (PF) corrected AC/DC controller designed for off-lineTRIAC dimmable LED lighting applications.The DX3580adopts high precise LED current controlling that it is intendedfor non-isolated Buck and Buck-Boost applications.
The DX3580 implements a unique LED currentcontrolling algorithm to maintain accurate output current regulation.The DX3580 operates in Boundary Conduction Mode(BCM) with the valley switching and power factorcorrection features to get easy Electromagnetic Interference(EMI) and low total harmonic distortion.
The DX3580 built-in multiple protections: Softstart-up,OCP,UVLO, high temperature foldback, OVP and Output short-circuit protection.
