Overview

® RT6033A 4-CH Constant Current LED Driver for Display Backlight General Description The RT6033A is a 4-CH constant current sink LED drivers with Dynamic Headroom Control (DHC) function.
RT6033A 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 ripple is kept as small even during the dimming.
The RT6033A provides four channel constant currents with less than 3% differences in output current value among the 4-CH and ICs respectively.
The constant current is adjustable by each channel external resistor (RISET).
The LED brightness can also be adjusted via th...
