产品概述 返回TOP
The CXLE8647 is a constant current regulator for driving LEDs with low quiescent current and low dropout voltage. The current is adjustable from 10mA to1A 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. The driver pin EXT is provided for current and voltage extension. Adding an external NMOS or NPN transistor to this pin can extend current and voltage range
