Preliminary YB1315 High Efficiency Charge Pump White LED Driver Description The YB1315 charge pump is designed to drive up to 5 white LEDs with regulated constant current in backlight display application. The device can provide up to 25mA per LED for a total 5 channels. The output current can also be combined into one single channel with 125mA output current for flash-light applications. The input voltage ranges from 2.7V to 5.5V and is ideal for applications powered by a single Li-Ion or 3 to 4 NiCd, NiMH or Alkaline batteries. YB1315 monitors the power-supply input voltage and LED forward voltage and current, and does an automatic selection to a switching mode that is optimized for the power conversion efficiency as well as battery operating time.
