International Rectifier has announced that its digital power chipset featuring GUI-based VR design for system-level optimisation powers the 3-way digital X79 motherboards from Gigabyte.
 
“We were able to implement an extremely high performance overclocking feature set using IR’s unique range of technologies. As a result, IR’s easily implementable, highly efficient and effective system-level solution was exceptionally well suited to our all digital 3D Power X79 Series of motherboards,” said Henry Gao, v-p of the Gigabyte motherboard business unit.
 
“We engineered enormous flexibility and superior voltage regulation into our controllers, allowing the customer and their customers to overclock these newest complex processors and DDR memory to levels that were not possible with analog or hybrid digital control,” said Deepak Savadatti, v-p and general manager, IR’s Enterprise Power Business Unit.
 
Featuring Dynamic Phase Control (DPC) and Variable Gate Drive (VGD) technology, IR’s true digital solution is designed for efficient delivery of power to the processor over the entire load range. 

The CHiL digital controller eliminates many external components necessary using hybrid digital or analog controller solutions to offer an extremely small, high density solution that allows incremental space on the motherboard to add extra system-level features, says the supplier.
 
The IR digital platform features a non-linear control architecture (adaptive transient algorithm, ATA) to allow best dynamic response with reduced output capacitor count to keep up with the demanding and highly variable workloads of the processor.

Its true digital engine allows superior on-the-fly performance optimization across the full operating range and even above the range of the processor without the need to modify hardware, while maintaining fully stable operation. The solution also provides a full suite of telemetry via built-in I2C digital interface to offer real-time monitoring of voltage, current, temperature and power to fully optimize and maximize power delivery to the processor.
