Monolithic Power Systems

Monolithic Power Systems, Inc. is an American semiconductor company specializing in power-management solutions for electronic systems. Founded in 1997 by Michael Hsing, the company designs, develops, markets, and supports digital, analog, and mixed-signal integrated circuits. Its portfolio is centered on power conversion and control, particularly energy-efficient DC-to-DC converter ICs, while also covering lighting control, audio amplification, and other functions used to regulate, distribute, and manage electrical power inside complex products. The company serves a broad range of end markets. Its components are used in cloud-computing and data-center equipment, storage systems, telecommunications infrastructure, automotive electronics, industrial machinery, consumer devices, displays, networking equipment, and medical equipment. MPS also supports vehicle electrification and supplies products for automotive power architectures. Typical applications include voltage regulation in computers and servers, power delivery in wireless-LAN access points, set-top boxes and displays, backlighting for LCD panels, power systems in vehicles, and electronic control systems used in industrial and communications equipment. MPS began under the leadership of Michael Hsing, who had previously worked in silicon-technology development at analog integrated-circuit companies. The company initially built its business around power-management technology and subsequently expanded into DC-to-DC products and additional product families. Hsing led the company through its November 2004 initial public offering. Over time, MPS developed a portfolio described as comprising 13 product lines and more than 4,000 products, reflecting a strategy of serving multiple applications with a broad range of highly integrated power devices rather than focusing on a single end market. The company sells through a mixed distribution model. It uses third-party distributors and value-added resellers while also maintaining direct relationships with original equipment manufacturers, original design manufacturers, and electronic manufacturing service providers. Its direct commercial activity spans the United States, Europe, China, Taiwan, South Korea, Southeast Asia, and Japan. MPS operates in more than 15 locations worldwide, with a footprint concentrated in the United States, Europe, and East Asia. MPS is positioned as a specialist supplier of high-performance, energy-efficient, and highly integrated power solutions. Its value proposition is based on helping equipment designers reduce component count, improve energy efficiency, manage thermal and electrical constraints, and integrate power functions into increasingly complex systems. The company became a component of the S&P 500 in February 2021. It has also reported environmental, social, and governance initiatives, including goals to reduce Scope 1 and Scope 2 greenhouse-gas emissions by 40 percent by 2030 and to reach 75 percent renewable electricity globally by 2026. The company’s public identity remains closely associated with power-management semiconductors and the engineering support required to embed them in computing, automotive, industrial, communications, and consumer products.

Monolithic Power Systems was established in 1997 by Michael Hsing. Before founding the company, Hsing worked as a senior silicon-technology developer at several analog integrated-circuit companies. His background informed MPS’s focus on highly integrated power-management semiconductors and helped shape the company’s engineering-led identity. The company developed products for regulating and converting electrical power in electronic systems, later diversifying into DC-to-DC products. This expansion allowed MPS to address a wider range of applications, including portable electronics, wireless-network equipment, computing systems, displays, automotive electronics, and industrial and medical equipment. Rather than operating as a general-purpose semiconductor manufacturer, MPS built its business around power circuits and adjacent functions that help equipment manufacturers improve energy efficiency, simplify system design, and control voltage and current. In November 2004, Hsing led the company through its initial public offering. Following the IPO, MPS continued expanding its product portfolio and market coverage. The company’s offerings came to include digital, analog, and mixed-signal integrated circuits, with particular emphasis on DC-to-DC conversion, power control, lighting management, and audio amplification. The portfolio was later described as comprising 13 product lines and more than 4,000 products. MPS serves a wide set of industries. Its power circuits are used in cloud-computing and storage infrastructure, telecommunications equipment, automobiles, industrial systems, consumer electronics, displays, and products associated with transportation electrification. Lighting-control products support backlighting in notebook computers, monitors, navigation systems, and LCD televisions. Class-D audio amplifiers extend the company’s reach into audio systems, while automotive and industrial products address the increasing demand for efficient and reliable power management in electronically controlled systems. The company’s commercial model combines indirect and direct sales. It markets products through third-party distributors and value-added resellers, while also selling directly to original equipment manufacturers, original design manufacturers, and electronic manufacturing service providers. Its direct market coverage includes China, Taiwan, Europe, South Korea, Southeast Asia, Japan, and the United States. MPS operates in more than 15 locations worldwide, primarily across the United States, Europe, and East Asia. A significant corporate milestone occurred in February 2021, when MPS was added to the S&P 500. In 2023, the company reported continued work on long-term ESG and diversity objectives, including the addition of a second female director to its board. It also published an annual ESG report and announced goals to reduce Scope 1 and Scope 2 greenhouse-gas emissions by 40 percent by 2030 and to obtain 75 percent of its global electricity from renewable sources by 2026. The company was subsequently reported as joining the Nasdaq-100 in December 2025. Across its development, MPS has remained focused on power-management technology as electronic systems have become more connected, computationally intensive, electrified, and energy-conscious.
