Overview

Preliminary Datasheet EIGHT-CHANNEL CONSTANT CURRENT SINK WITH CURRENT MATCH General Description Features AP3609 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 channel.
The LED light can be adjusted by PWM dimming function.
The device can keep working when LED opens without damage.
It features under voltage lockout protection and over temperature protection.
The AP3609 has two interface terminals (FB and FBX).
They enable the device to be connected in parallel.
The AP3609 is available in SOIC-16 package.
· 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 Protecti...
