Product Details

The MAX77812 evaluation kit (EV kit) 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
  • Four outputs in 1 + 1 + 1 + 1 phase configuration

A Micro-B USB cable can be connected between the EV kit and a PC for easy testing of the I2C interface. 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.
