Power Solutions for Intel® IMVP6.5 Platform

The Intel Mobile Voltage Positioning 6.5 (IMVP-6.5) specification provides power management information for the Intel® processors utilizing this platform. Integrated solutions provided by Texas Instruments are fully compliant single-phase synchronous DC/DC buck regulators especially designed for use in low-power CPUs and Intel integrated Graphics solutions for computing systems. Advanced control features in TI power management products include D-CAP architecture and OSR overshoot reduction for faster transient response, lowest output capacitance and higher efficiency. Other important features include 5-bit graphics VID rendering, and adjustable control of VCORE slew rate and voltage positioning.

With the addition of power MOSFET CICLON NexFET™ technology to the TI power management portfolio, we can now provide a low on resistance coupled with an extremely low gate charge with industry-standard package outlines a combination not previously possible with existing silicon platforms. NexFET technology delivers high performance for both N- and P-channel power MOSFET devices. Designers are able to achieve 90-percent power supply efficiencies from light to full loads with high output currents and low duty cycles, representing a breakthrough in discrete designs.

Double the frequency, without a power loss penalty

In synchronous buck-converter power supplies used in computing, networking and server systems, the power MOSFET is a critical element in DC/DC efficiency. When compared to industry standard trench-type power MOSFETs with the same on resistance, NexFET technology delivers less than half the gate charge (Qg). Lower charge means that converters can run at higher frequencies while maintaining the same power loss or run more efficiently at the same frequency. Such a large reduction in gate charge enables a potential doubling of power supply switching frequency, which delivers a reduction of as much as half the size of the power supply output filter, saving precious board space and reducing component count and ultimately, cost.

Reduced operating temperatures

NexFET technology enables power MOSFETs to run more efficiently (up to 30-percent cooler) and also allows the MOSFET driver to run considerably cooler. The end result is as much as 15-percent cooler, improving the overall reliability of the system.
