The MAX25221 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB used to evaluate MAX25221 and MAX25221B automotive 4-Channel TFT-LCD Power Supply with VCOM Buffer or the MAX25220 automotive 4-Channel TFT-LCD Power Supply without VCOM. Each output rail (AVDD, NAVDD, VGON, VGOFF and VCOM) can be independently adjusted via I²C. The EV kit demonstrates the device’s features: adjustable output voltage, fault protection, VCOM temperature compensation, and non-volatile memory programming. The EV kit exposes an I²C interface which can operate in conjunction with the MINIQUSB+ adapter or a third party I²C master like a general-purpose microcontroller. The EV kit also includes Windows^®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the IC. The EV system includes both the EV kit and the MINIQUSB+ adapter board.
