Product Brief
CP2162 V1.0
LED Driver Series
6 Channel, 1X/1.5X Common Anode Adaptive Charge Pump Parallel
LED Driver with 1-Wire Pulse Counting Dimming Control
www.datasheet4Gu.econmeral Description
The CP2162, a 1X/1.5X common anode 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
CP2162 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 CP2162, which can guarantee a constant LED current in
various operating conditions. The CP2162 uses the 1-wire pulse
counting technique to adjust the brightness of LEDs, with the pulse
signal on the EN/SET pin, the LED current varies according to 32 steps
logarithmic scale. Only two 1µF input/output capacitors and two 1µF
flying capacitors are needed for proper operation. The superior
architecture ensures low inrush current and low EMI. The CP2162
adopts 3mm*3mm QFN 16L package.
