Commercialization of VRM Controllers (since 1997)

Within the next two years many companies developed and introduced commercial products in the form of integrated controller to support the multi-phase VRM approach.

This new multi-phase VRM has now been adopted by the entire industry as standard practice. A large number of companies have come up with integrated power semiconductor devices and controls (ICs) to support the multiphase concept. Companies such as Fairchild, Siliconix, Texas Instruments, National Semiconductor, Semtech, Intersil, ON Semiconductor, Linear Technology, Maxim, Primarion, Silicon Labs, Analog Devices, Volterra, Microsemi and STMicroelectronics, have produced integrated control ICs for the multiphase solutions. These products are used to power the current and future generation of microprocessors.
