Monolithic Power Systems designs tiny parts and modules that deliver the right amount of electricity inside servers, cars, computers, networks and everyday electronics. Its center of gravity is moving quickly toward the machines behind artificial intelligence, while its older computer and consumer lines are growing more slowly. It designs rather than owns the factories, and most sales pass through a small group of distributors.

Enterprise Data
Power systems for artificial-intelligence chips and servers. In Q2 FY2026, sales jumped 164.3% from a year earlier to $380.6 million; watch whether customer approvals turn that burst into durable shipments rather than a single fast ramp.
Competes with Digital controllers and switching parts that feed processors (Renesas) · High-density converter modules for server power (Infineon) · Vertical power modules placed close to processors (Vicor)
In plain English
Picture the power strip behind a giant computer, shrunk down and built around its hungriest chips. Enterprise Data includes the controllers, conversion blocks and compact modules that take electricity from a server and feed each processor exactly what it needs.
Makers of artificial-intelligence processors, server boards and complete servers approve MPS parts for a design, then buy units as they build those machines. More power-hungry processors need more parts and denser modules, so MPS can earn more from each server. The approval process makes a winning design sticky, but losing one can quickly cut shipments.
Communications
Power parts inside the fast network boxes that connect data centers. Q2 FY2026 sales rose 78.3% from a year earlier to $131.6 million; watch whether newer, faster links keep pulling more MPS parts into each box.
Competes with Temperature controllers, switches and power modules for glass-fiber links (Analog Devices) · Telecom power-converter blocks and local regulators (Texas Instruments)
In plain English
Every burst of data between computers passes through boxes that steer traffic and small modules that send it through hair-thin glass cables. MPS supplies the parts that lower, steady and protect the electricity inside those boxes and modules.
Network-switch and optical-module makers choose these parts while designing new equipment. Distributors then supply the chips and compact power assemblies as that equipment enters production. Faster connections pack more electronics into tight spaces, creating more places for MPS to sell. Delayed data-center construction or a slow changeover to the next network speed pushes those sales out.
Storage and Computing
Electricity-management parts for computers, memory boards and storage machines. FY2025 sales climbed 46.0% to $732.5 million, but first-half FY2026 fell 2.5%; new high-speed memory orders must outrun weak notebook demand.

In plain English
The unglamorous job here is keeping a computer's many parts fed without wasting electricity or damaging them. MPS sells chips and modules that adjust power for notebooks, desktop computers, memory boards and storage hardware. Its newer parts also help very fast memory communicate and receive power.
Computer makers, memory suppliers and storage-equipment companies approve MPS inside a product, then order through distributors as they assemble it. A successful placement can repeat for the life of that model. Sales still rise and fall with notebook replacements and memory inventories, so newer high-speed memory wins are the route to steadier growth.
Automotive
Power, sensing, motion, lighting and sound parts for cars. FY2025 sales rose 43.1% to $592.5 million, yet Q2 FY2026 growth slowed to 8.2%; watch how quickly newly shipping places in vehicle designs become volume sales.

In plain English
A modern car needs dozens of small electrical gatekeepers. MPS parts feed cameras and dashboard screens, move motors, manage batteries, drive lights and speakers, and protect circuits when something goes wrong.
Automakers and the suppliers that build major car systems test and approve each part for a specific place in a vehicle design. Once that car enters production, MPS is paid for every chip or module shipped, mostly through distributors. Those approvals can produce sales for years, but they take a long time and depend on how many vehicles the customer ultimately builds.
Consumer
Power and control parts for televisions, monitors, game systems, appliances and portable devices. Q2 FY2026 sales slipped 4.8% from a year earlier to $56.8 million; its job is breadth, not leading the present growth surge.
Competes with InnoSwitch appliance and adapter power chips (Power Integrations) · Wall-power switching and display-light parts (Texas Instruments)
In plain English
Open a television, game system or kitchen appliance and electricity must be converted, divided and sent to the right places. MPS supplies the chips that do that work, plus parts that control screens, backlights, charging and speakers.
Device and appliance makers select the parts for each model; distributors keep enough on hand for many customers and replenish them as products sell. High production runs can create a lot of unit sales, but buyers are price-conscious and can cut orders quickly when store demand weakens. This is a broad base of everyday uses, not the company's current growth center.
Industrial
Power and motion parts for factories, robots, buildings, clean-energy equipment and medical machines. FY2025 sales grew 35.3% to $199.4 million; watch approved designs become orders, because management described FY2026 mainly as a placement-winning year.

In plain English
Factories need motors to turn precisely, robots to stop safely and measuring equipment to receive clean, steady electricity. MPS combines power parts with motor controls, battery monitors, sensors and signal-reading chips so an equipment maker can buy more of the electrical system from one supplier.
Engineers approve those parts while building a machine, often with help from MPS and its distributors. MPS earns when the customer later manufactures that design. Industrial products may stay in production for years, but testing and approval move slowly; winning a place today can mean meaningful shipments much later.
