CAT3606 Datasheet (ON Semiconductor) - 6-Channel Low Noise Charge Pump White LED Driver

CAT3606, 6-Channel Low Noise Charge Pump White LED Driver

The CAT3606 controls up to four LEDs for the main display and two LEDs for the sub-display in cellular phones.

The device is capable of operating in either 1x (LDO) mode or 1.5x charge pump mode.

All LED pin currents are regulated and tightly matched to achieve uniformity of brightness across the LC
