MAX16928 Evaluation Kit
Evaluates: MAX16928
General Description
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.
