Data Sheet 5 CHANNEL CHARGE PUMP CURRENT SINK FOR LED DRIVER AP3615 General Description The AP3615 is a step-up DC-DC converter based on 1x/1.5x charge pump and low dropout current sink, which helps it maintain the highest efficiency. The AP3615 is specially designed to drive up to 5 WLEDs in backlight display. The AP3615 provides up to 20mA current for each WLED. There are totally 16 steps of current control, which is achieved through a digital pulse dimming function on EN pin. Additionally, 1MHz high switching frequency enables the use of small external capacitors. Internal soft-start circuitry prevents excessive inrush current during start-up and mode transition. The supply voltage of AP3615 ranges from 2.8V to 5.
