    描述

    The MAX8973A evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX8973A. The EV kit allows for easy evaluation of each MAX8973A features.

    The MAX8973A is a high-efficiency, three-phase, DC-DC step-down switching regulator that delivers up to 9A of output current in a compact footprint with excellent transient response. Each phase operates at a 2MHz fixed frequency, allowing the use of small magnetic components. Maxim Integrated’s proprietary Rotational Phase Spreading algorithm optimizes efficiency at low output currents. Software-selectable forced-PWM mode allows either fixed-frequency operation, or improved efficiency at light load with a variable frequency in skip mode. The triple- inductor architecture reduces the size of the external components while providing the benefit of ripple current cancellation. An I2C 3.0-compatible serial interface, supporting clock rates up to 3.4MHz, controls key regulator parameters such as output voltage, output slew rate, and on/off control. An EN input enables and disables the output, while a DVS pin selects two different output voltages without relying on the serial interface. MAX8973A fully differential remote sense ensures precise DC regulation at the point of load.

    Windows® based software provides a user-friendly interface to exercise the features of the MAX8973A. This software offers a graphical user interface (GUI) as well as a register-based interface.
