Abstract: The present disclosure shows a hybrid regulator topology that can be more easily integrated and that can maintain high efficiency across a wide output and input voltage range, even with a small inductor. The hybrid regulator topology can include two types of regulators: a flying switched-inductor regulator and a step-down regulator that divides the input voltage into an M/N fraction of the input voltage. The disclosed embodiments of the hybrid regulator topology can reduce the capacitive loss of the flying switched-inductor regulator by limiting the voltage swing across the switches in the flying switched-inductor regulator. The disclosed embodiments of the hybrid regulator topology can reduce the inductor resistive loss of the flying switched-inductor regulator by operating the flying switched-inductor regulator at a high switching frequency and with a small amount of current flow through the inductor.

Abstract: The present disclosure shows ways to use multiple “integrated voltage regulator (IVR) units” to offer IVRs that can cover a wide range of specifications without having to design separate IVRs for different specifications. Instead of designing separate IVRs and paying for separate mask sets for IVRs targeting different specifications (e.g., different design and mask sets for 1 A IVR, 5 A IVR), the disclosed embodiments present ways to design and fabricate large numbers of the same unit IVRs (e.g., 1 A IVR) and decide how many of them to use post-fabrication to deliver different current specifications (e.g., use five 1 A unit IVRs for 5 A, use ten 1 A unit IVRs for 10 A). These disclosed embodiments reduce the mask cost of fabricating IVRs for different specifications and reduce design time by focusing on a single unit IVR.
