AAT2820 | Triple Output Charge Pump Regulator

The AAT2820 is a member of AnalogicTech's Total Power Management ICTM (TPMICTM) 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. An additional regulated output voltage is provided for biasing the Display module. Built-in soft-start circuitry prevents excessive inrush current during start-up. A high switching frequency enables the use of very small external capacitors. A low shutdown feature disconnects the load from VIN and reduces quiescent current to less than 0.1A. The AAT2820 is available in a Pb-free TDFN44-16 package and is specified over the -40C to +85C operating temperature range.
