Limerick based provider of IC solutions for energy control and management in information processing systems, Powervation, has announced the availability of the PV3002, which the company claims is the industry's first Auto-control digital power-conversion IC.
The PV3002 is targeting electronic systems used in computing, netcomms and storage applications where the device aims to bring automatic adaptive control to DC-DC conversion for the first time. The company says the new device offer designers of power supplies an intelligent 'no compromises' solution that is impervious to variations in component values and applications context, making it easier to build complex designs that conform to today's energy-efficient standards.
At half the size of comparative analog solutions, the PV3002 can reduce total system component counts by as much as 50 percent. This advantage cuts system costs and improves Mean Time Before Failure (MTBF). In beta tests at multiple customer sites, the chip demonstrated efficiency gains of more than 10 percent for light-load configurations while improving stability and transient performance. Moreover, at the system level, the PV3002 enables digital power management at no extra cost, delivering energy savings of up to 30 percent and reducing overall cost of ownership by 30 percent.
Powervation's Auto-control technology empowers engineers with new ease-of-design capabilities and eliminates the time-consuming challenge of accounting for the production tolerances of all components in the control loop. Unlike conventional analog regulators that use external components and require complex calculations to compensate the controller, Powervation's Auto-control regulates and monitors the output voltage on a cycle-bycycle basis and automatically compensates for variations in line, load, capacitance and inductance. The key driver of this capability is 'MOJO', a single parameter that is used to adjust the loop compensation (poles, zeros and gain) to guarantee stability and best performance. The result is 'true' adaptive control that eliminates the need for the designer to compensate the control loop. For designers of power supplies, the plug-and-power approach can cut design time from weeks to days.
With Auto-control at its core, the PV3002 is custom-built for computing, netcomms, storage and other applications where a more efficient power supply has become a key competitive differentiator.
In advanced networking equipment such as mid-range Ethernet switches where there may be as many as 150 different voltage rails in a single switch fabric, optimizing power management across the entire system is complex. With true adaptive control, the PV3002 is able to intelligently distribute the power, enabling the system to consistently operate at peak efficiency.
Powervation's Vice President of Marketing, Benoit Herve, said the PV3002 represents a fundamental shift in power-supply design and solves the most pressing performance, reliability and cost challenges facing designers.
"It is the first product in the industry to reliably adapt power conversion to changing system behavior and unpredictable variations, and guarantees unprecedented stability over a wide range of conditions throughout the lifetime of the system. Customers report that with Auto-control, they can breach the performance barriers that have limited traditional digital power technologies - a breakthrough that offers unprecedented ease-of-use and new efficiency advantages," commented Herve.
