资 源 简 介

The QX7136 is a constant  current regulator for driving LEDs with low quiescent current and low dropout voltage. The current is adjustable from 10mA to 400mA with an external resistor.  Only one external resistor is required to achieve a constant current LED driver. Soft start, thermal protecTIon and low voltage protecTIon are also provided. A driver pin DR is provided for current and voltage extension. Adding an external NMOS or NPN transistor to this pin can extend current and voltage range.
