Product Brief
CP2163A V1.0
DC/DC Series
High Efficiency 1X/1.5X Fractional Charge Pump for White LED
www.daOtasVheEet4Ru.cVomIEW
The CP2163A is optimized for white LED supplies in backlit color
display applications. The device provides a constant current, set by
an external resistor, for each LED. The supply voltage ranges from
2.7 V to 5.5 V and is ideally suited for all applications powered by a
single LI-Ion battery cell or three to four NiCd, NiMH, or Alkaline
3mm*3mm QFN 16L
-40℃~85
battery cells. The CP2163A provides up to 30 mA per LED, for a total of 120 mA, for input
voltages ranging from 3 V to 5.5 V. High efficiency is achieved by utilizing a 1x/1.5x adaptive
fractional conversion technique in combination with very low dropout current sources. Only two
external 1µF and two 0.47 µF capacitors are required to build a complete small and low cost power
supply solution. The CP2163A switches at 1 MHz operating frequency and is available in a small
16-pin QFN package to keep board space to a minimum.
FEATURES
