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.
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.
The MAX9550 is available in a space-saving 5-pin thin
SOT23 package, and an 8-pin µMAX® package with an
exposed paddle. The MAX9551 is available in an 8-pin
µMAX package with an exposed paddle. The MAX9552
is available in a 14-pin TSSOP package. All devices are
specified over the -40°C to +85°C temperature range.
