AP3607 - 4/6 CHANNEL CHARGE PUMP CURRENT SINK

Download the AP3607 datasheet PDF. This datasheet also covers the AP3606 variant, as both devices belong to the same 4/6 channel charge pump current sink family and are provided as variant models within a single manufacturer datasheet.

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.

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.
