Preliminary QX7135 Constant Current LED Driver QX7135 General Description THE QX7135 is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage. The current ranges from 100mA to 400mA with 10mA step. No external com ponent is required to achieve a constant current LED driver. Soft start, therm al protection and low voltage protection are also provided.
