CP2142 4-Channel Low-Dropout Constant-Current Parallel LED Driver

The CP2142, a 4-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 CP2142, which can guarantee a constant.

CP2142 Features

* y y y y y y y y y y No external component required Only 100mV dropout voltage needed at 20mA per channel 1-wire pulse counting dimming: 16 steps logarithmic scale LED current matching: ±2% (typical) Over 90% efficiency can be reached No EMI and switch noise Thermal shutdown protection Supply voltage
