Analog Devices / Maxim Integrated MAX25221EVKIT Evaluation Kit

Analog Devices Inc. MAX25221EVKIT Evaluation Kit is a fully assembled and tested surface-mount PCB used to demonstrate the MAX25221 Automotive 4-Channel TFT-LCD Power IC with VCOM Buffer, and by extension, the MAX25220 Automotive 4-Channel TFT-LCD Power IC without VCOM. Each output rail (AVDD, NAVDD, VG_ON, VG_OFF, and VCOM) can be independently adjusted via I²C. The MAX25221EVKIT demonstrates the device’s features, including adjustable output voltage, fault protection, VCOM temperature compensation, and non-volatile memory programming.
