Preliminary Datasheet

EIGHT-CHANNEL CONSTANT CURRENT SINK WITH CURRENT MATCH

AP3609

General Description

Features

The AP3609 is an eight-channel constant current sink

with current match used for LED driver. It uses an

external resistor to set the current for eight LED strings

with an accuracy of ±1.5%. The full scale LED current

can be adjusted from 10mA to 100mA for each chan-

nel. The LED light can be adjusted by PWM dimming

function.

Input Voltage Range: 4.2V to 5.5V

Typical Output Current: 480mA (60mA/1V per

Channel)

Maximum Output Current: 800mA (100mA/1.5V

per Channel)

Current Match Accuracy: ±1.5%

PWM Dimming Control

Open LED Self-check and Protection

Under Voltage Lockout Protection

Over Temperature Protection

Enable Parallel Application

The device can keep working when LED opens with-

out damage. It features under voltage lockout protec-

tion and over temperature protection.

The AP3609 has two interface terminals (FB and

FBX). They enable the device to be connected in paral-

lel.
