Ferric integrated voltage regulators (IVRs) bring voltage regulation closer to the processor, shortening the power delivery path compared with a conventional power delivery network (PDN). This reduces loop inductance, parasitic impedance, and reliance on bulk capacitance while enabling higher-bandwidth power delivery. The result is faster transient response and more stable voltage during rapid load changes, helping minimize voltage droop as AI processors transition between power states. In the example above, Ferric demonstrates a 100 A/100 ns load step with less than 40 mV of voltage droop.
