AP3031 Datasheet (DIODES) - WHITE LED STEP-UP CONVERTER

AP3031, WHITE LED STEP-UP CONVERTER

The DIODES™ 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 ti
