Analog Devices / Maxim Integrated MAX25221EVSYS Evaluation System

Analog Devices Inc. MAX25221EVSYS Evaluation System is a platform for evaluating the performance of the MAX25221 Automotive 4-Channel TFT-LCD Power Supply with VCOM Buffer and MAX25220 Automotive 4-Channel TFT-LCD Power Supply without VCOM. The MAX25221EVSYS System demonstrates each device’s features, including adjustable output voltage, fault protection, VCOM temperature compensation, and non-volatile memory programming.

ADI MAX25221EVSYS Evaluation System offers an I2C interface, allowing operation in conjunction with the MINIQUSB+ adapter or a third-party I2C master. The Kit provides Windows®-compatible software that provides a simple graphical user interface (GUI) for utilizing the features of the IC. The MAX25221EVSYS Evaluation System includes both the EV kit and the MINIQUSB+ adapter board.
