6.2.1 TI Sequencer Studio Software

The PC-based Texas Instruments Sequencer Studio software communicates with the device via a PMBus interface, and enables the design engineer to configure the operating parameters for the application. This is done without having to learn low level PMBus commands. The software saves the configuration to on-chip nonvolatile memory, and can be used to observe system status during debug efforts. After configuration, the device will perform independently on startup. Download the Sequencer Studio software from the UCD91320 web page.
