Meeting the Challenges of Power-Supply Design for Modern High-Current CPUs

摘要

The performance capabilities of Intel~® and AMD~® CPUs have increased dramatically over the past five years. This rise in performance has driven growth in the sophistication and complexity of the voltage regulators that power the CPU. The biggest challenge facing power-supply designers is keeping up with increases in power levels, tighter tolerances, and faster transient requirements, while reducing the overall cost of the power supply.
