FEATURES

DESCRIPTION

Complete LTPS-LCD Bias Solution

Triple Output Charge Pump Providing

at 16 mA, V at 2 mA, V at 1 mA

The TPS65110/11 is a very compact power supply

solution providing the three voltages required by many

LTPS LCD displays.

2.4 V to 5.5 V Input Voltage Range

Fixed Output Voltages of 3.3 V, 7.5 V, −2.7 V

or 5.0 V, 9.0 V, −3.0 V

50 µA Typical Quiescent Current

Less Than 1 µA Shutdown Current

All three regulated outputs are generated using a charge

pump topology.

The VCC charge pump provides precise, high efficiency,

and very low ripple dc/dc conversion for the LCD analog

power. The VCC boost ratio (x1.0, x1.33, x1.5, and x2.0)

is automatically set based on input and output voltage

conditions. The VCC output assures 16 mA of current by

using three 0.22-µF flying capacitors. If the required output

current is smaller, smaller capacitors can be applied.

Ultra-Low Ripple (V

= 5 mV,

Typical at 5 mA)

Autonomous Boost for V

Supply

1.5% Accuracy on Fixed VCC Output Voltage

Sequential Power Control

24-Pin QFN Package (4 x 4)

The VDD charge pump provides a higher positive voltage,

and the VSS charge pump provides the negative output

voltage. Power up/down sequences are internally set and

are secured even in cases of sudden and abnormal VIN

drop.

APPLICATIONS

Small Form LTPS−LCD Displays

PDAs, Pocket PCs

Smart Phones

One of the most significant features of the TPS65110/11

is the ultra-low output voltage ripple, as the VCC charge

pump achieves 5-mV output ripple voltage.
