POWER INTEGRATIONS INC

POWER INTEGRATIONS INC (None, CIK 0000833640) — US-listed company materially exposed to Power Electronics.

Power Integrations designs and sells high-voltage analog and mixed-signal integrated circuits for power-conversion applications. The company’s historical focus is AC-DC power conversion, where it integrates a high-voltage power MOSFET into a controller IC. The business model is generally fabless or fab-lite: the company designs the chips and works with outside foundries for wafer fabrication and assembly/test providers.

Qualitative claims below are based on cached knowledge and are not primary-source verified for this output:

• Revenue mix by segment (%): needs primary source validation

The company has historically reported one operating/reportable segment, so segment-level revenue mix may not be available from a segment note. Product-family or end-market mix may be discussed in MD&A. Exact percentages require the 10-K MD&A or supplemental investor disclosures and must be cross-verified.

• Gross margin: needs primary source validation
• Operating margin: needs primary source validation
• Net income: needs primary source validation
• Revenue growth rate: needs primary source validation
• Monetization model: sells ICs to OEMs, EMS providers, and distributors; revenue is generated on product shipments. Exact revenue-recognition policy requires direct quotation from the 10-K revenue recognition footnote.
• Who pays: power-supply OEMs, consumer-electronics OEMs, appliance makers, industrial equipment makers, LED lighting manufacturers, and distributors.
• Top customers from filings only: needs primary source validation

The 10-K should be checked for customer concentration, distributor concentration, and whether any customer exceeds 10% of revenue.

Because I could not retrieve actual units shipped or revenue, I cannot compute POWI’s actual ASP or unit economics. The formula to run once primary data is retrieved is:

\[

\text{ASP per unit} = \frac{\text{net revenue from product sales}}{\text{units shipped in the same period}}

\]

If units shipped are not directly disclosed, a fallback is:

\[

\text{revenue per end-equipment unit} = \frac{\text{segment revenue}}{\text{estimated end-equipment shipments}}

\]

Sensitivity example, once inputs are available:

\[

\text{Market share estimate} = \frac{\text{POWI AC-DC revenue}}{\text{global AC-DC power-conversion IC TAM}}

\]

Sensitivity table for market share:

Because the inputs are unverified, I will not insert a numerical result. In a live-raised version, each input would need either a direct filing citation or a named-institution market estimate.

From a filings-only perspective, the correct place to identify customers is:

• 10-K “Customers” or “Concentration of Credit Risk” note
• MD&A customer concentration disclosure
• 10-K risk factor on customer concentration
• Occasionally, named distributor relationships

Cached narrative — not primary-source verified — is that POWI sells to:

• Consumer-electronics OEM/ODM supply chains, including those producing AC adapters, chargers, quick-charge/USB-PD accessories, and appliances
• LED lighting suppliers
• Industrial power-supply makers
• Distributors, potentially including large electronics distributors such as Arrow or Avnet

However, I will not assert specific customer names because I could not verify them against the filing. In a compliant version, named customers must come directly from the 10-K or another Tier-1 filing.

Customer classes/buyer archetypes:

• Power-supply design engineers selecting AC-DC converter ICs
• Procurement teams at ODM/EMS companies
• Distributor central-listed customers
• OEM platform designers in appliances, computing, mobility, and industrial equipment

All of the above must be re-checked against the actual 10-K customer concentration and MD&A sections.

Every missing value above must be replaced with an exact figure plus the document identifier, filing date, and access date before this report can be considered Tier-1 compliant.
