AP3605 Overview
Features The AP3605 is a step-up DC/DC converter based on 1.5x charge pump current source, it is specially designed for LED supplies in backlight display. The AP3605 can provide constant current up to 20mA for each LED, which is programmed by an external resistor, so it has a total capability to provide 80mA for 4 LEDs. The chip has a good performance of LED current matching and allows PWM brightness dimming control.
