DESCRIPTION

The A707 is a high voltage Boost driver with 3 channels adjustable constant current regulators for notebook LED backlight applications. Three regulated current ports are designed to provide uniform and pure DC constant current sinks for driving LEDs within a large range VF variations. It can drive a number of LEDs in series/parallel configuration
