Product Details

The MAX20428 evaluation kit (EV kit) is a fully assembled and tested application circuit for the MAX20428 high-efficiency eight-output low-voltage PMIC. The EV kit can test each of the outputs to full load within the normal operation input range of +3V to +4.2V. The IC features two modes of watchdog operation: challenge/response and simple windowed mode. These can also be disabled for simplified evaluation. I2C communication must be used to configure the MAX20428 and monitor errors. A PC-to-I2C interface (such as the MINIQUSB or MAX32625PICO) and software for reading and writing to I2C registers (such as SimpleI2C) will simplify testing.
