RT6033 Datasheet

RT6033 4-CH Constant Current LED Driver

The RT6033 is a 4-CH constant current sink LED drivers with Dynamic Headroom Control (DHC) function. RT6033 can provide well current matching ability, adjustable VSET to choose the suitable dropout voltage across the MOS / BTJ. Beside that, DHC will provide the stable VFB dimming, thus voltage rippl.

Features

include Short LED Protection (SLP), Open LED Protection (OLP) and Over Temperature Protection (OTP). When any channel triggers protection function, LED will be turned off and the FAULT pin will pull low. The RT6033 is available in SOP-16 package to achieve optimized solution for PCB space.
