The AP3606 and AP3607 are step-up DC-DC converters based on 1x/1.5x charge pump and low dropout current sink, which helps them maintain the highest efficiency. The AP3606 is specially designed to drive up to 4 WLEDs in backlight display while the AP3607 is designed for 6 WLEDs. These devices provide up to 20mA current for each WLED. There are totally 16 step.
