FP6787/A

Integrated Multi-Channel DC-DC Converter

for TFT LCD Panel

Description

Features

The FP6787/A offers a compact power supply

solution to provide all voltages required by thin-film

● High Efficiency

● Low Power Consumption

● 2.7V to 5.5V Input Supply Voltage

transistor (TFT) LCD panel.

The FP6787/A

includes a high performance boost regulator, a low

dropout linear regulator (LDO), a voltage detector, a

VCOM buffer (unity-gain OPA), a positive charge

pump and a negative charge pump to provide

adjustable regulated output voltages.

640kHz Current-Mode Boost Regulator

● Fast Transient Response to Pulsed Load

● Adjustable Output Voltage with ±1% Accuracy

● Built-In 16V, 3A, 0.2Ω N-Channel MOSFET

● High Efficiency up to 85%

● Built-in 8ms Soft-Start

● Over-Current Protection

The boost converter provides the regulated supply

voltage for the panel source driver ICs.

The

converter is a 640kHz current-mode regulator with

an integrated 16V N-Channel 0.2Ω MOSFET. It

provides fast transient response to pulsed loading

while achieving efficiency over 85%. The device

can produce output voltage as high as 14V from an

input as low as 2.7V. FP6787/A includes internal

8ms soft start.

● Over-Voltage Protection

Low Dropout Linear Regulator

● 600mA Maximum Output Current

● Fixed Output Voltage : 3.3V (FP6787)and 2.5V

(FP6787A)

● ±2% Output Voltage Accuracy

Low Voltage Detector

The low dropout (LDO) linear regulator can supply

up to 600mA current while input voltage is 5V. It

uses an internal PMOS as the pass device. It is

suitable for the supply voltage of the timing

controller.

● Programmable Detection Voltage

● ±2% Detection Voltage Accuracy

● Programmable Reset Delay Time

● Push-Pull Output

The voltage detector monitors the supply voltage to

issue a reset signal while the detected voltage is too

low. The detecting level is decided by an external

resistor divider and the delay time is programmable

by an external capacitor.

Unity-Gain Operation Amplifier for VCOM Buffer

● Rail-to-Rail Input and Output

● 12V/µs Slew Rate and 12MHz Bandwidth

● 250mA Short-Circuit Current

● Charge Pump for VGH Regulation

● Charge Pump for VGL Regulation

● Over-Temperature Protection

● TSSOP-20 And TQFN-20 Exposed Pad Packages

● RoHS Compliant

The VCOM buffer can drive the LCD VCOM voltage

that features high short-circuit current (250mA), fast

slew rate (12V/µs), wide bandwidth (12MHz) and

rail-to-rail inputs and outputs.

The positive charge pump controller provides

Applications

regulated TFT gate-on voltage.

The negative

● Notebook Computers Displays

● LCD Monitor Panels

charge pump controller provides regulated TFT

gate-off voltage. The regulation of the positive and

negative charge pump is generated by the internal

comparator that senses the output voltage and

compares it with an internal voltage reference.
