UNISONIC TECHNOLOGIES CO., LTD L16B45A Preliminary 16-BIT CONSTANT CURRENT LED SINK DRIVER CMOS IC „ DESCRIPTION The UTC L16B45A is designed for LED displays. UTC L16B45A contains a serial buffer and data latches which convert serial input data into parallel output format. At UTC L16B45A output stage, sixteen regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of Vf variations. UTC L16B45A provides users with great flexibility and device performance while using UTC L16B45A in their system design for LED display applications, e.g. LED panels. Users may adjust the output current from 3mA to 45mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs.
