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 components. The default LED current is adjustable by an external resister at FB pin and the feedback voltage is regulated to 200mV typically. The AL3050 provides PWM dimming mode and single wire digital dimming mode for accurate LED current.
