High-Current VCOM Drive Buffers

for TFT LCDs

General Description

Features

The MAX9550/MAX9551/MAX9552 provide a VCOM

source for TFT LCDs. The MAX9550/MAX9551/

MAX9552 source and sink a large current to quickly

restore the VCOM voltage, making it ideal for TFT LCDs.

The output settles to within 0.1% in less than 2µs. In

addition, the MAX9550/MAX9551/MAX9552 directly drive

the capacitive load in the VCOM layer of the TFT LCDs

without the need for a series resistor.

♦ Operates Up To 20V

♦ 800mA Peak Output Current

♦ Settles to Within 0.1% of V

♦ Excellent Load Regulation

in Less than 2µs

OUT

♦ Thermal-Shutdown Protection

♦ Short-Circuit Protection to Both Rails

♦ Soft-Start to Reduce Inrush Current

The MAX9550/MAX9551/MAX9552 feature single, dual,

and quad channel VCOM amplifiers, respectively. The

MAX9550/MAX9551/MAX9552 can drive up to 800mA of

peak current per channel and operate up to 20V. The

devices feature soft-start to reduce inrush current, output

short-circuit protection, and thermal shutdown.
