AP3019A Datasheet (BCD Semiconductor) - WHITE LED STEP-UP CONVERTER

AP3019A, WHITE LED STEP-UP CONVERTER

The AP3019A is an inductor-based DC/DC converter designed to drive up to eight white LEDs in series for backlight.

Only one feedback resistor is needed to control the LED current and obtain required brightness.

A constant frequency 1.2MHz PWM control scheme is employed in this IC, which means tiny e
