The LT®1943 is a highly integrated, 4-output regulatordesigned to power large TFT LCD panels. The LT1943employs switching regulators—instead of linear regulators—to minimize power dissipation and accommodate awide input voltage range. The wide input range, 4.5V to22V, allows it to accept a variety of power sources,including the commonly used 5V, 12V and 19V AC adaptors.
