AP3606数据手册集成电路（IC）的LED驱动器规格书PDF

描述 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 W°Cs in backlight display while the AP3607 is designed for 6 W°Cs.

These devices provide up to 20mA current for each W°C. 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-3Ω3-16.
