Datasheet Summary
SMALL PANEL BACKLIGHT LED DRIVER
Description
The AL3050 is a current mode Boost-type LED driver with programmable brightness dimming control for portable devices. With a 30V rated integrated MOSFET and power diode, the AL3050 can support up to 8 LEDs in series. The small solution size, advanced dimming Features and high efficiency are suitable for LED backlight solutions for single cell Li-ion based equipment. The boost converter runs at 750kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external ponents.
The default LED current is adjustable by an external resister at FB pin and the feedback voltage is...
