YB1315 High Efficiency Charge Pump White LED Driver

YB1315 Description

Preliminary YB1315 High Efficiency Charge Pump White LED Driver .
The YB1315 charge pump is designed to drive up to 5 white LEDs with regulated constant current in backlight display application.

YB1315 Features

* Voltage Input Range From 2.7V to 5.5V
* Drives From 3 to 5 LEDs at Up to 25mA
* Each Fractional Conversion Modes for High Conversion Efficiency, 1x and 1.5x 1MHz Internal Oscillator Thermal Protection Shutdown Output Short-

YB1315 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 f
