The CXLE8180 is a 4-channel ultra low dropout constant source parallel LED driver. The CXLE8180 uses an internal resistor to set the bias current for four LEDs.
The CXLE8180 incorporates a single wire interface to program the output current at 16 continuous steps. It has an internal deglitch circuit for filtering the noise of the EN input.
The CXLE8180 requires only a 35mV dropout voltage at a 20mA load. The feature makes CXLE8180 ideal for battery-operated systems, such as personal digital assistants.
The CXLE8180 is available in Green TQFN-3?-16L, TDFN-2?-8L and MSOP-8 packages and is specified over an ambient
