Ferric’s Integrated Voltage Regulators make Complex Power Systems Simple

Medium Load SoC example with multiple Rails

This example requires 336A for the Main Rail. Ferric achieves this with just (6) Fe1736s in parallel with no external circuitry. The Secondary Rail requires only one Fe1736 and the other rails can be handled with just one Fe1728.

Systems with up to 1500A for a single domain are achievable using Ferric Fe1736 PVRs.

High Power Chiplet example with 2 Rails

In this example Ferric devices are powering a chiplet array. Each CPU/GPU uses 0.70V at 26As on its main rail and 0.9Vs at 3 As for its secondary rail. This sub-array of 8 CPU/GPU chiplets is powered with just 4 Fe1736s for the primary rail and just 1 Fe1728 for the secondary rail. An architecture type like this allows for very granular DVS control as voltage scaling can be implemented individually for each CPU/GPU pair for both rails. This allows for maximum power savings.

In this instance a larger array of 48 CPU/GPU chiplets totaling over 1400As with 24 separately controllable domains is shown.

Infinitely Scalable for Chiplet Architectures

The example above is easily scalable to a 96 CPU/GPU chiplet system using over 2800As of power or even a 144 CPU/GPU chiplet system using over 4200As.
