General Description

The ADD8754 is optimized for use in TFT LCD applications, requiring only external charge pump components to provide all the requirements for panel power, VCOM, and gate modulation.

Included in a single chip are a high frequency step-up dc-to-dc switching regulator, logic voltage regulator, VCOM amplifier, and gate pulse modulation circuitry.

The step-up dc-to-dc converter provides up to 20 V output and includes a 2 A internal switch.

Key Features

Step-up switching regulator with 2 A power switch 650 kHz or 1.2 MHz switching frequency Output adjustable to 20 V 350 mA logic voltage regulator Selectable output voltages: 2.5 V, 2.85 V, 3.3 V VCOM amplifier with 300 mA drive Gate pulse modulation circuitry Independently adjustable delay and falling slope General 3 V to 5.5 V input Undervoltage lockout Thermal shutdown 24-lead, Pb-free LFCSP package.
