Free GUI from Intersil cuts design time for power systems

Intersil Corp. has unleashed its latest free, downloadable graphical user interface (GUI) that helps system designers quickly configure, validate and monitor their power supply architectures. According to the company, the additional features included in PowerNavigator 5.2 enable a high degree of power supply optimisation.

Combined with the drag-and-drop GUI interface, PowerNavigator 5.2 makes it straightforward to change features and functions of a digital power supply design without writing a single line of code.

PowerNavigator 5.2

The PowerNavigator 5.2 software GUI allows for configuration and monitoring of Intersil's portfolio of PMBus-enabled digital power products including digital regulators, controllers, multiphase devices, power modules and digital power monitors. Using a PC, USB interface and a few mouse clicks, designers can configure and change any parameter, telemetry or rail sequencing for their digital power supply. The PowerNavigator version 5.2 includes three innovations:

1. PowerMap adds more real-time information to the power rail blocks, such as device name, phase count, output voltage, output current, PMBus addresses and current sharing capability. This additional information helps users more quickly visualise their system. PowerMap's realistic system level view, with zoom-in/out and scrolling, replicates a system with multiple power rails delivering point-of-load current to ASICs, processors, DSPs or FPGAs.

2. Rail Inspector quickly guides users through the power supply parameters set up. Rail Inspector brings up rail name and shows the number of devices, device address and status, as well as important supply parameters: input voltage, switching frequency, output voltage and load current. Device options include clock synchronising, sequencing and current sharing. Users can then load and save configuration files in both text and hex formats.

3. RailScope simplifies system validation, giving users the ability to plot all device telemetry such as input voltage, output voltage, output current and temperature for up to four rails at a time. RailScope's system logging feature automatically logs telemetry and fault data for later analysis.
