Michael Hsing built a power-chip company around integration: the history of Monolithic Power Systems
Michael Hsing founded Monolithic Power Systems in 1997 in California after working in analogue semiconductor design.
The company concentrated on high-performance power-management chips that could integrate functions traditionally spread across multiple components.
The early business looks very different from the company visible today. Following the milestones in order shows which decisions changed Monolithic Power Systems’s direction and which capabilities remained constant.
DC-DC conversion became the first durable franchise
MPS built switching regulators and power-conversion products used to efficiently deliver the different voltages required inside electronic systems.
This was an important turning point because it expanded what Monolithic Power Systems could offer or the markets it could address. The effect becomes clearer when viewed as part of the longer sequence of changes that followed.
The 2004 IPO funded a broader analogue portfolio
Monolithic Power Systems went public in 2004. It expanded into motor drivers, lighting, battery management and other mixed-signal products while keeping power efficiency at the centre.
For Monolithic Power Systems, access to public markets was more than a branding milestone. It increased financial transparency and created another route to fund expansion, acquisitions or long-term product development.
Consumer electronics gave way to more diversified end markets
The company broadened exposure across industrial, automotive, communications and computing customers, reducing dependence on any one consumer-device cycle.

AI servers increased the value of efficient power delivery
Modern accelerators and CPUs draw very high currents, making voltage regulation and power density critical system-design challenges. MPS consequently gained greater relevance to data-centre and AI infrastructure.
The AI era increased the value of capabilities Monolithic Power Systems had already been developing. Compute, data, networking, software or infrastructure that once served narrower workloads became relevant to much larger AI systems.
Every faster processor still needs better power
As of 18 September 2026, monolithic Power Systems remains focused on power-management and mixed-signal semiconductors rather than trying to become a general-purpose processor company. Founder Michael Hsing continues as chief executive, giving the company unusual leadership continuity.
The company’s current position is therefore the result of accumulated technical and commercial choices rather than one breakthrough product. That is the context future coverage should preserve.
For TechnologyBlog.co.za, this page is intended to serve as the company-history cornerstone for future Monolithic Power Systems coverage, so product and company-news articles can link back to one factual brand background instead of repeating the full origin story.
