The MAX16928 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 boost converter, a 3.3V regulator controller with external npn transistor, two gate voltage regulators, a single-stage positive charge pump, and a single-stage negative charge pump.
The EV kit can operate from 4.5V to 5.5V input voltages and is optimized for automotive TFT-LCD applications. The boost converter is configured for a 12V output that provides at least 400mA. The regulator controller output is 3.3V and provides at least 500mA. The positive-gate voltage regulator provides 18V output and the negative-gate voltage regulator provides -5.9V.
