Product Details

The MAX77511/MAX77711 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates either the MAX77511 or MAX77711 powermanagement integrated circuit (IC).

The EV kit is a step-down voltage regulator circuit using the IC that allows for easy evaluation of each feature. The circuit is capable of 2.3V to 10V input, 3A/phase continuous load, and output voltage adjustable between 0.25V and 5.2V. The EV kit evaluates either MAX77511 or MAX77711. Both ICs are the same except MAX77711 includes a 300mA LDO.

The EV kit supports evaluation of each converter phase (Φ) configuration:

  • 4Φ (single 12A output)
  • 3Φ + 1Φ (9A output + 3A output)
  • 2Φ + 2Φ (6A output + 6A output)
  • 2Φ + 1Φ + 1Φ (6A output + 3A output + 3A output)
  • 1Φ + 1Φ + 1Φ + 1Φ (four 3A outputs)

Three on-board transient loads allow users to exercise the full capability of the buck regulator or LDO. Windowsbased software provides a friendly graphical user interface (GUI) as well as a detailed register-based interface to exercise all the features of the IC.
