APPLICATION NOTE

NVM Programming for VR13 Power Controllers

NVM Programming for VR13 Power Controllers

TPS53679, TPS53659, TPS53622 are Intel™ VR13 Serial VID (SVID)-compliant power supply controllers that have programmable parameters. This guide also applies to proprietary footprint devices TPS53678, TPS53658 TPS53655, as well as TPS53681, even though it is not an Intel power controller. The PMBus interface configures the parameter values which are stored into non-volatile memory (NVM) as new boot-up default values. This guide gives a tutorial on NVM programming, and the tools TI provides for the programming process. This guide applies to all the devices in the TI VR13 controller family.

1 Introduction

This guide gives an overview of NVM programming for the following TI VR13 controller devices: TPS53679, TPS53659, TPS53622, TPS53678, TPS53658, TPS53655 and TPS53681. Local TI sales and field applications representatives can provide relevant documentation to these devices. This guide gives a technical overview and step-by-step instructions.

1.1 Software Tools

1.1.1 Fusion Digital Power Designer

Fusion Digital Power Designer is a graphical user interface (GUI) that configures and monitors Texas Instruments digital power controllers, sequencer monitors, and health monitors. The GUI uses the PMBus protocol to communicate with the device over a serial bus using a proprietary USB adapter.

Use the Fusion Digital Power Designer GUI for engineering development. The GUI gives access to all available user-configurable settings, fault information, and telemetry readings. After you configure the device, you can export the settings to a configuration file. The export options are:

  • System file (.tifsp) contains configuration data for all of the devices in a system
  • Project file (.xml) contains configuration data for a single device
  • PMBus programmer script (.csv) is a text file containing step-by-step programming instructions for non-TI software tools

1.1.2 Fusion Manufacturing Tool

The Fusion Manufacturing Tool is a graphical user interface (GUI) that programs TI digital power controllers in a production environment. Download the latest copy of the Fusion Manufacturing Tool from this URL: http://www.ti.com/tool/fusion_mfr_gui

1.1.3 Online and Offline Modes

The Fusion Digital Power Designer software operates in online mode when you have connected a device to the system that hosts the software. The software operates in offline mode when you have not connected a device to the system that hosts the software. The software installer provides a different shortcut for each mode.

1.1.4 Relevant File Formats

Table 1. Configuration File Formats

File Description Extension Type Compatilble Software
Fusion project file Contains configuration data for a single device. Intended for engineering development. .xml plain-text XML Fusion Digital Power Designer
Fusion system file Contains configuration data for multiple devices. Can be used in engineering development, and production programming. .tifsp plain-text XML Fusion Digital Power Designer, Fusion Manufacturing Tool
PMBus programmer script Simplified programming script (comma separated format) for production environment. .csv plain-text comma separated value Fusion Digital Power Designer and third-party tools

1.2 Hardware Tools

1.2.1 USB-to-GPIO Dongle

Both Fusion Digital Power Designer and Fusion Manufacturing Tool GUIs use the TI USB-GPIO adapter to interface between a host computer and controller devices. Use this link to get a TI USB-GPIO adapter: http://www.ti.com/tool/usb-to-gpio.

2 Technical Overview

This section shows how to program NVM with the TI software tools, or with non-TI tools.
