A8440 Datasheet | AiT Semiconductor

AiT Semiconductor Inc. .ait-ic. 4CHANNEL WHITE LED DRIVER 1x /1.5x CHARGE PUMP DISPLAY BACKLIGHT SOLUTION DESCRIPTION Features The A8440 is a plete backlight display solution that is designed to independently control LEDs. The A8440 is a charge pump WLED driver capable of driving up to 4 LEDs with 30mA each LED. Its four tightly regulated current sources ensure excellent LED current and brightness matching. LED driver current is programmed by an external resistor. The A8440 operates over an input voltage range from 3V to 5.5V, optimized for WLED applications powered by Li-Ion battery, requiring only for low cost ceramic capacitors. The A8440 provides excellent efficiency...
