GUI-Based Design Tool for Digital Controllers Simplifies DC/DC Converter Design
Intuitive Design Tool Uses PMBus™ Commands to Digitally Program and Configure More than 60 Power Supply Parameters
Cork, Ireland, and San Jose, CA, November 15, 2011: Powervation Ltd., the pioneer in adaptive digital power management IC solutions that increase system efficiency, improve field reliability, and accelerate time to market, today announced the release of PowerSMART™, the Setup, Monitor, And Reporting Tool for the design of digital power converters.
The PowerSMART tool allows users to communicate with and configure the Powervation digital power control ICs (e.g., PV3012) from PC & MAC platforms using a standard USB connection. The design tool enables the user to program the controller and optimize its performance, while carefully monitoring key power supply status parameters. Users may use the tool to make simple point-and-click or numeric entry changes to parameters and quickly configure/power-up the power supply. Additionally, users may take advantage of its advanced settings to access more than 60 parameters and finely tune the features to their specific needs within the GUI environment, with precision and flexibility beyond that of hardware programmed analog-based solutions.
The GUI-based design tool can connect and control multiple devices in a system concurrently. For a single device used in a single- or dual-phase converter, users will utilize the Single Mode feature of the design tool. The PowerSMART design software also provides a System Mode feature where multiple Powervation devices can be used in parallel to control a multi-phase converter (e.g., 6 phases), and multiple Powervation devices can be used within a common platform to provide power management for multiple rails and the sequencing of these rails.
The framing of the GUI display provides status and fault indicators that are available to the user at all times. The main PowerSMART display page has been designed to provide a heads-up view of VOUT, VIN, and IOUT against a time axis, so that users may view these key parameters the way engineers typically see them displayed on today's popular digital oscilloscopes. Additionally, the Monitoring indicator box on the main page summarizes, numerically, the current telemetry information for temperature (IC and external sensors), current, and voltages, giving the user easy access to this data for both design and debugging activities.
Comments David New, Director, Product Marketing, Powervation Inc., "During the design stage, the GUI-environment allows users to easily select and program the desired parameters, while helping users fully utilize the capabilities of our digital controllers without coding or training. From engineers that desire to use the tool's automatic setup, to users that need advanced optimization and access to dozens of parameters, the software supports a wide range of users." Additionally, Powervation's control ICs, such as the recently-launched PV3012, are equipped with Powervation's Single Pin CONFIG™ technology that provides the user access to eight configuration tables, or profiles, within the IC's non-volatile memory. Each of the eight configuration tables can be configured within the tool, and allows the user access to more than 60 parameters that may be used when designing a power supply. Using the device's on-board configuration profiles allows a single controller to be used in up to eight converters, and eliminates the need to configure the part through PMBus or via multiple external programming components. The PowerSMART tool provides users flexible access to this feature, and many more, in a simple and intuitive environment, that has been designed to be usable for engineers new to digital power, as well as those already well on their way.
