Abstract

A power management integrated circuit and a method of operation thereof are provided. The power management integrated circuit (PMIC) includes: a DC-DC converter configured to provide output power to a load; a controller configured to control switching of the DC-DC converter; and a sensing circuit including a capacitive element and configured to detect an output current flowing through a node between the DC-DC converter and the load.

Description

[0001] This application claims the priority of Korean Patent Application No. 10-2020-0069838 filed on June 9, 2020 and Korean Patent Application No. 10-2021-0054635 filed on April 27, 2021, said Korean Patent Application The entire subject matter of the application is hereby incorporated by reference. technical field [0002] The inventive concept relates generally to a power management integrated circuit (PMIC), and more particularly, to a PMIC including a detection circuit having a capacitive element capable of extending an operating bandwidth of the PMIC. Background technique [0003] PMICs have become important components in numerous consumer products such as smart phones, tablet personal computers (PCs), and the like. Such products, many of which are mobile or battery operated, require efficient power management. That is, minimizing power consumption and improving power efficiency are important aspects of PMICs in mobile devices. Switching regulators, such as pulse-wi...
