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.
