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.

Description

[0001] Cross References to Related Applications [0002] This application is based on 35 U.S.C. § 119(e) requirements filed April 11, 2013 entitled "SYSTEMSANDMETHODSFORPROVID IN GAHYBRIDVOLTAGEREGULATOR", the entire contents of which are incorporated herein by reference. [0003] Statement Regarding Federally Sponsored Research or Development [0004] This invention was made with government support under Grant 1248828 awarded by the National Science Foundation (NSF). The government has certain rights in this invention. technical field [0005] The present disclosure relates to devices, systems and methods for providing hybrid voltage regulators. Background technique [0006] There is a strong need to reduce the size of electronic systems. Size reduction is especially desirable in mobile electronic devices where space is at a premium, but is also desirable in servers that are placed in large data centers, since it is important to cram as many servers as possible into ...
