Introduction

AI Translation

OB3330X is a primary-side feedback LED constant-current driver controller with high power factor correction, designed for flyback isolated LED lighting applications. Eliminates the need for secondary-side components such as TL431 and optocouplers. Operating in critical conduction mode to minimize switching losses and maximize efficiency.

Features

AI Translation
