RT6033 - 4-CH Constant Current LED Driver

General Description

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.

Key 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. Simplified.

® RT6033 4-CH Constant Current LED Driver for Display Backlight General Description 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 ripple is kept as small even during the dimming. The RT6033 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 the EN/PWM pin with PWM dimming duty from 1% to 100%.
