Description

The TPS536C7EVM evaluation module (EVM) allows users to evaluate the TPS536C7 controller.

The controller is dual-channel (12 + 0, 11 + 1 or 10 + 2 phases), D-CAP+™ synchronous buck driverless control with PMBus Interface. The device operates using a voltage supply between 4.5 V and 17 V. The (...)

Features
  • Configurable to 12+0, 11+1 or 10+2 phases
  • Test support for high power (400A) ASIC
  • Support for dynamic load
  • Thermal balance
  • Flexi-phase management

Software development

APPLICATION SOFTWARE & FRAMEWORK Download
Digital Power Software
FUSION_DIGITAL_POWER_DESIGNER Fusion Digital Power™  is the Graphical User Interface (GUI) used to configure and monitor select Texas Instruments digital power controllers and sequencer/health monitors. The application uses the PMBus protocol to communicate with the device over serial bus by way of a TI USB adapter.
Features

Some of the tasks you can perform with the GUI include:

  • Turn on or off the power supply output, either through the hardware control line or the PMBus OPERATION command
  • Monitor real-time data. Items such as input voltage, output voltage, output current, temperature, and warnings/faults are continuously (...)
