Step-Up White-LED Driver
OVERVIEW
The CP2126 is a step-up DC, DC converter specifically designed to drive white LEDs with a constant current. The device can drive two, three or four white LEDs in series from a Li-Ion cell. Series connection of LEDs provides identical LED currents resulting in uniform brightness. The CP2126 switches at 900KHz, allowing the use of tiny components. The external capacitor can be as small as 0.
