Tools and Documentation

The application firmware for UCD3138 is developed on Texas Instruments Code Composer Studio (CCS)

integrated development environment (v3.3 recommended).

Device programming, real time debug and monitoring/configuration of key device parameters for certain

power topologies are all available through Texas Instruments’ FUSION_DIGITAL_POWER_DESIGNER

Graphical User Interface (http://www.ti.com/tool/fusion_digital_power_designer).

The

FUSION_DIGITAL_POWER_DESIGNER

software

application

uses

the

PMBus

protocol

communicate with the device over a serial bus using an interface adaptor known as the USB-TO-GPIO,

available as an EVM from Texas Instruments (http://www.ti.com/tool/usb-to-gpio). PMBUS-based real-time

debug capability is available through the ‘Memory Debugger’ tool within the Device GUI module of the

FUSION_DIGITAL_POWER_DESIGNER GUI, which represents a powerful alternative over traditional

JTAG-based approaches.

The software application can also be used to program the devices, with a version of the tool known as

FUSION_MFR_GUI optimized for manufacturing environments (http://www.ti.com/tool/fusion_mfr_gui).

The FUSION_MFR_GUI tool supports multiple devices on a board, and includes built-in logging and

reporting capabilities.
