MAX77812EVKIT#

The MAX77812EVKIT# is an evaluation kit (EV kit) for MAX77812. It is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77812. The EV kit allows for easy evaluation of each feature. It supports user-programmable phase configuration to one of five options: single output in 4 phase configuration (default), dual outputs in 3 + 1 phase configuration, dual outputs in 2 + 2 phase configuration, three outputs in 2 + 1 + 1 phase configuration and four outputs in 1 + 1 + 1 + 1 phase configuration. A Micro-B USB cable is included in the package to serve as the USB to I2C interface for easy testing. Windows® based software provides a user-friendly interface to exercise the features of the MAX77812. This software offers a graphical user interface (GUI) as well as a register-based interface.
