Product Details

The MAX20067 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that provides the voltages and features required for automotive thin-film transistor (TFT), liquid-crystal display (LCD) applications. The EV kit includes a synchronous boost converter, double-stage positive charge pump, double-stage negative charge pump, VCOM buffer, and gate-shading push-pull switch. The EV kit can operate from 2.7V to 5.5V input voltages and is optimized for automotive TFT-LCD applications. The EV kit can be configured to operate in stand-alone mode or in I2C mode. The boost converter is configured for a 12V output that provides at least 200mA. The positive-gate voltage regulator provides 16V output and the negative-gate voltage regulator provides -6V. The VCOM buffer provides an I2C-adjustable output voltage initially biased at 6V.

The EV kit provides an I2C interface that can operate in conjunction with the MINIQUSB+ adapter board or a third-party I2C master, such as a general-purpose microcontroller. The EV kit also includes Windows®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the IC. The EV system includes both the EV kit and the MINIQUSB+ adapter board.
