CP2141 3-Channel Low-Dropout Constant-Current Parallel LED Driver

The CP2141, a 3-channel low-dropout constant-current parallel LED driver, can be used to drive white LED, red LED, blue LED or any color LED whose forward operating voltage is lower than the battery voltage. The unique Auto-MirrorTM technology is introduced in CP2141, which can guarantee a constant.
