A8440 Features

* The A8440 is a complete 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 c

A8440 Applications

* powered by Li-Ion battery, requiring only for low cost ceramic capacitors. The A8440 provides excellent efficiency by operating the charge pump in a gain of 1 or 1.5. Maximum efficiency is achieved over Li-Ion battery voltage range by selecting the proper gain based on the LED forward voltage requir
