General Description
The AAT2820 is a member of AnalogicTech's Total
Power Management IC (TPMIC) product fam-
ily. It is a triple output charge pump targeted for
active matrix thin-film transistor (TFT), liquid crys-
tal displays (LCDs), and CCD camera bias for sys-
tems operating with lithium-ion/polymer batteries.
The device generates three regulated output volt-
ages for turn-on gate drive bias (V
POS
), turn-off
gate voltage bias (V
NEG
), and logic voltage.
The V
POS
and V
NEG
output voltages are independ-
ently 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 V
IN
and
reduces quiescent current to less than 0.1μA.
The AAT2820 is available in a Pb-free TDFN44-16
package and is specified over the -40°C to +85°C
operating temperature range.
