Datasheet Summary
Triple-Output Charge Pump Regulator General Description
The AAT2820 is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. It is a triple output charge pump targeted for active matrix thin-film transistor (TFT), liquid crystal displays (LCDs), and CCD camera bias for systems operating with lithium-ion/polymer batteries. The device generates three regulated output voltages for turn-on gate drive bias (VPOS), turn-off gate voltage bias (VNEG), and logic voltage. The VPOS and VNEG output voltages are independently regulated. Both outputs use external diode and capacitor multiplier stages (as many stages as required) to regulate output voltages up to +25V and -25V....
