AP3031 WHITE LED STEP-UP CONVERTER

The AP3031 is an inductor-based DC/DC boost converter designed to drive LED arrays. 1.4A switching current allows AP3031 to be used in different 7' to 10' LCD panel backlights (3 *13 LED arrays typically). A constant frequency 1MHz PWM control scheme is employed in this IC, which means tiny exter.
