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,
