AP3009 Datasheet (BCD Semiconductor) - WHITE LED STEP-UP CONVERTER

AP3009, WHITE LED STEP-UP CONVERTER

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
