Abstract: Uses the MAX641 switching controller and an external discrete charge pump to step up the input voltage. This circuitcan service low loads and is efficient when the output is two, three, four times the input voltage. Adding the MAX627 MOSdriver can further increase the output current capability.

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.
