General Description
The AAT3190 charge pump controller provides the
regulated positive and negative voltage biases
required by active matrix thin-film transistor (TFT)
liquid-crystal displays (LCDs), charge-coupled
device (CCD) sensors, and organic light emitting
diodes (OLEDs). Two low-power charge pumps
convert input supply voltages ranging from 2.7V to
5.5V into two independent output voltages.
The dual low-power charge pumps independently
regulate a positive (V
POS
) and negative (V
NEG
) out-
put voltage. These outputs use external diode and
capacitor multiplier stages (as many stages as
required) to regulate output voltages up to ±25V.
Built-in soft-start circuitry prevents excessive in-
rush current during start-up. A high switching fre-
quency enables the use of small external capaci-
tors. The device’s shutdown feature disconnects
the load from V
IN
and reduces quiescent current to
less than 1.0μA.
The AAT3190 is available in an MSOP-8 or
TSOPJW-12 package and is specified over the
-40°C to +85°C operating temperature range.
