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.
