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...
