| Evaluates MAX9552 MAX9552 Evaluation Kit The MAX9552 evaluation kit EV kit is a fully assembled and tested surface-mount PCB that contains a MAX9552 IC. The MAX9552 has four high-current VCOM drive buffers for TFT LCDs. The outputs are capable of driving large capacitive loads and settle to within of VOUT in less than 2µs. The MAX9552 operates from a 7V to 20VDC power supply. Each channel can source or sink 800mA of transient load current.

Follow the steps below to verify board operation. Caution Use low-impedance cables to connect the power supply to the VDD and GND pads on the EV kit. Do not turn on the power supply until all connections are completed. 1 Set the power-supply output to 16V and turn off the power supply. 2 Connect the power-supply ground to the GND pad on the EV kit. 3 Connect the power-supply output to the VDD pad on the EV kit. 4 Turn on the power supply. 5 Verify that all the outputs OUTA, OUTB, OUTC, and OUTD are approximately 8V. 6 Use low-impedance cables when connected to external loads. Detailed Description The MAX9552 EV kit is a fully assembled and tested surface-mount PCB that contains a MAX9552 IC. The MAX9552 is a quadruple high-current VCOM buffer for driving TFT LCDs. Each buffer is capable of sourcing or sinking large transient load current to quickly restore the VCOM voltage, making the MAX9552 an ideal buffer for driving large capacitive loads in TFT LCDs. The MAX9552 EV kit outputs OUTA, OUTB, OUTC, and OUTD are set to VDD / 2 by voltage-divider resistors respectively. To set the outputs to other voltages from 2V to VDD - 2V , select different voltagedivider resistors. The MAX9552 EV kit provides four test points INA-, INB-, INC-, and IND- to accept external feedback from a remote-sense node, and then applies it to the negative input terminals of the buffers. To use external feedback sensing, cut open the PCB trace that runs directly between the respective negative input test point and the output pad, and connect the external feedback sense line to the selected test point INA-, INB-, INC-, and IND- .
