Analog Devices / Maxim Integrated MAX20028EVKIT Evaluation Kit

Analog Devices MAX20028EVKIT Evaluation Kit is a fully assembled and tested circuit for evaluating the MAX20028 power-management IC (PMIC). The MAX20028 Power Management Integrated Circuit (PMIC) is a 2.1MHz, multichannel, DC-DC converter designed for automotive applications. The Evaluation Kit includes one high-voltage step-down controller and two low-voltage step-down converters.

The ADI MAX20028EVKIT Evaluation Kit operates from 3.5V to 36V input voltages and is optimized for automotive infotainment applications. The high-voltage controller is configured for a 5V output that provides at least 5A. The low-voltage step-down converters are configured for 3.3V and 1.2V, each providing up to 3A.

The MAX20028EVKIT Evaluation Kit can be easily reconfigured to operate in continuous PWM mode, skip mode, or external synchronization operation. The Evaluation Kit includes the MAX20028ATJA/VY+ PMIC and is capable of evaluating other variants of the MAX20028 IC.
