International Rectifier has introduced a new digital power platform designed to improve energy efficiency in a wide variety of applications, including high-performance server, desktop and computing applications. The new family offers a fully compliant high-speed serial bus to meet new industrial requirements. These 5-, 6- and 8-phase dual output PWM controllers, in which phases are flexibly assigned between loops 1 and 2, can be configured for Intel VR12, AMD SVI/PVI/G34 and feature switching frequency between 200 kHz and 1,2 MHz per phase. Features include variable gate drive, dynamic phase control, adaptive transient algorithm on both loops, auto phase detection with auto compensation and per-loop protection features.
