Overview

Data Sheet 4/6 CHANNEL CHARGE PUMP CURRENT SINK FOR LED DRIVER AP3606/AP3607 General Description 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 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 ranges of AP3606 and AP3607 are from 2.
7V to 5.
5V which make them ideally suit for applications powered by Li-ion battery.
These ICs are available in the tiny package of QFN-3×3-16.
Features • Regulated Output Current with ±3% Matching •...
