[Outline]
This IC is a white LED driver IC. It is a step-up DC-DC converter IC designed to drive up to 7 LEDs and suitable for backlight drivers. Feedback voltage is as low as 95mV, which can reduce power consumption in a current set resistor. A small 0.22µF capacitor can be used, so that not only space but costs can be reduced.


[Features]
1. Enables to drive up to 7 white LEDs in a series connection
2. Input voltage range     2.5 to 6.0V
3. Shutdown current       0.1µA typ.
4. High efficiency             85% typ.
5. Luminance control       PWM system
6. Feedback voltage        95mV
