Evaluation Kit for the MAX17122 (MAX17122EVKIT) (MAX17122EVKIT)

The MAX17122 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that provides the voltages and features required for thin-film transistor (TFT), liquid-crystal display (LCD) TV panels. The EV kit includes a step-down regulator, step-up regulator, negative output buck-boost regulator, positive regulated charge pump, and a negative linear regulator.

The MAX17122 IC operates from +10V to +14V input voltages and is optimized for LCD TV panels running directly from +12V supplies. The step-up switching regulator is configured for a +15V output that provides at least 2.2A with an input voltage of +12V. The step-down regulator is configured for a +3.3V output that provides at least 2.5A and the buck-boost is configured for a temperature-variable -12V to -20V output that provides at least 450mA. The positive regulated charge pump is configured for a +28V output providing at least 100mA. The negative linear regulator is configured for a -7.5V output providing at least 100mA.
