Supply Meets Demand: Use Multiphase Converters to Solve Tough Power Design Challenges (.PDF Download)

No matter what the latest microprocessor, FPGA, or ASIC has in store, their demands always seem to be the same—the need for higher current while operating at lower voltages. A core voltage of less than 1 V is common. Power supplies for current-generation microprocessors must be able to supply the core with a current up to 200 A. Dynamic load variations of up to 500 A/µs are also possible. During these transients, the voltage to the processors must stay within a narrow window,
