com General Description 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 LED current in various operating conditions.
The CP2141 uses the 1-wire pulse counting technique to adjust the brightness of LEDs, with the pulse signal on the EN pin, the LED current varies according to 16 ste...
