The MAX9550/MAX9551/MAX9552 are three VCOM drive buffers that provide a VCOM source for TFT LCDs. They can provide high current to quickly restore the VCOM voltage, making them ideal for TFT LCDs. The output settles to within 0.1% of VOUT in less than 2µs. In addition, the MAX9550/MAX9551/MAX9552 can directly drive the capacitive load in the VCOM layer of the TFT LCDs without the need for a series resistor. The MAX9550/MAX9551/MAX9552 are 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.
