RT8300 Datasheet | Richtek

® 4-CH 150mA Constant Current LED Driver General Description The RT8300 is a 4-CH 150mA constant current sink LED driver capable of driving four channel constant currents with good matching ability and wide range VF variations. The RT8300 provides four channel constant currents with less than 3% differences in output current value among the 4-CH and ICs respectively. The constant current output is adjustable from 5mA to 150mA via an external resistor (RISET). The LED brightness can also be adjusted via the PWMI pin with pulse width modulation from 0% to 100%. Thus allowing for wide VF variation. Moreover, the RT8300 provides Dynamic Headroom Control (DHC) function which can...
