Product Brief
CP2141 V1.1
LED Driver Series
3-Channel Low-Dropout Constant-Current Parallel LED Driver with
1-Wire Pulse Counting Dimming Control
www.datasheet4Gu.econmeral 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 steps logarithmic scale. Without any external
components, it is available in a tiny SOT23-6L package and is ideally
suitable for portable device applications.
