Multiphase 101

In today’s computing environment, CPUs, FPGAs, ASICs and even peripherals are growing increasingly complex and, consequently, so do their power delivery requirements. To handle the higher demands, multiphase regulators are becoming increasingly common on motherboards in many areas of computing--from laptops and tablets to servers and Ethernet switches. Designing with these regulators is more challenging than using conventional switchers and linear regulators, but the benefits of multiphase outweigh the complexity for high-performance power applications.
