AP3009 Description
The AP3009 is an inductor-based DC/DC converter designed to drive up to six white LEDs in series for backlight. Only one feedback resistor is needed to control the LED current and obtain satisfied brightness. A constant frequency 1.2MHz PWM control scheme is employed in this IC, which means the tiny external ponents can be used.
