Product Brief CP2160 V1.0 LED Driver Series 6 Channel, 1X/1.5X Common Cathode Adaptive Charge Pump Parallel LED Driver with 1-Wire Pulse Counting Dimming Control www.datasheet4u.com General Description The CP2160, a 1X/1.5X common cathode adaptive charge pump parallel LED driver, is ideally suited for all applications powered by a single LI-Ion battery cell with input voltage varying between 2.7V to 5.5V. The CP2160 provides up to 25mA LED current per channel, set by an internal resistor. High efficiency is achieved by utilizing a 1x/1.5x adaptive fractional conversion technique based on the supply voltage and the output voltage. The unique Auto-MirrorTM technology is introduced in CP2160, which can guarantee a constant LED current in various operating conditions.
