ADD8754 Datasheet (Analog Devices)

ADD8754, Gate Modulation

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 ampl
