APPLICATIONS

TFT LCD panels for TVs and monitors

GENERAL DESCRIPTION

The ADD8733 is a 4-channel regulator with two VCOM

amplifiers and gate pulse modulation (GPM) that provides

all the necessary voltages for thin film transistor (TFT) liquid

crystal displays (LCD). Included is a step-up regulator, a step-

down regulator for digital logic, two VCOM amplifiers, two

charge-pump regulators for VGH and VGL, and an integrated

gate pulse modulator.

By offering a complete power integration solution optimized for

TFT LCD TVs and monitors, the ADD8733 helps to lower cost,

simplify board design, and increase performance over existing

solutions.

The ADD8733 is offered in a 48-lead RoHS compliant LFCSP

and is specified over the industrial temperature range of −40°C

to +85°C.
