GALAXY GeForce GTX560 Ti White Edition: Albino Titano Pictorial

The GALAXY GeForce GTX560 Ti White Edition exemplifies a technical tour de force in terms of VRM design, in particular, its NVVDD VRM.
FBVDD power is delivered by a 2-phase VRM. MOSFETs are driven and controlled by uPI Semiconductor Corp.,’s uP6210 buck controller.
NVVDD power is supplied via a 6-phase Volterra DC-DC buck converter setup, consisting six Volterra VT1157 Smart Slave™ output devices. GALAXY claims that the NVVDD VRM on the GeForce GTX560 Ti White Edition delivers up to 240 A of NVVDD power.
The NVVDD VRM buck controller used on the GALAXY GeForce GTX560 Ti White Edition is the Volterra VT1185MF.
Key to every buck converter setup is its controller. A uPI Semiconductor Corp., uP7706 linear regulator isolates the VT1185MF from spurious switching noise, allowing robust VRM operation.
