Evaluation Kit for the MAX17102 (MAX17102EVKIT) (MAX17102EVKIT)

The MAX17102 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that provides the voltages and features required for active-matrix, thin-film transistor (TFT), liquid-crystal displays (LCDs). The EV kit contains an SMBus™-compatible interface, a step-up switching regulator, a positive charge pump, a negative charge pump, a VCOM amplifier with a digitally adjustable VCOM calibration device with nonvolatile memory, and seven high-voltage level-shifting buffers.

The MAX17102 EV kit operates from a DC supply voltage from +2.5V to +5.5V. The step-up switching regulator is configured for a +16V output providing at least 450mA from a +4.5V to +5.5V input. The positive charge pump is configured for a +30V output providing 50mA. The negative charge pump is configured for a -10V output providing 50mA. The VCOM calibrator is capable of providing up to ±150mA peak, and features a programmable output voltage initially configured for +7.2V. The high-voltage, level-shifting scan driver buffers seven logic inputs (A2–A8) and shifts them to a desired level (Y2–Y8) for driving TFT-LCD row logic.

The MAX17102 EV kit demonstrates low quiescent current and high efficiency (> 85%) for maximum battery life. Operation at 1.2MHz allows the use of tiny surface-mount components.

Windows® 2000/XP®- and Windows Vista®-compatible software is also available for use with the MAX17102 EV kit and can be downloaded from www.maximintegrated.com/evkitsoftware.
