Today’s desktop PC challenges power designers to provide a reliable yet cost effective voltage regulator (VR) solution with increasing demands for higher efficiency and flexibility. Desktop processors require high currents at low voltage levels, up to 130A at around 1.0V, due to their increased clock frequencies and smaller process geometries. The processor core voltage must remain within the strict regulation limits, under both DC and high-slew-rate current transient conditions. Violation of these specifications may result in a blue screen or reduced operating life.

International Rectifier provides unique digital VR Controllers and MOSFET drivers for interleaved multiphase buck converters to meet these demanding requirements

Performance PC’s used for gaming, high end graphics, satisfying a highly growing customer base of enthusiasts and overclockers, need to feature state-of-the-art performance. International Rectifier's unique feature set results in the highest possible performance of the CPU and Memory power subsystems.

By combining highly integrated features along with International Rectifier’s proven efficiency and thermal management features, the Enthusiast community can reach the highest levels of performance, user interface and reliability of their key CPU and Memory power subsystems.
