A leading supplier of parts for electronics such as home appliances, Power Integrations (NASDAQ:POWI) is a semiconductor designer and developer specializing in products used for high-voltage power conversion.
Demand for analog chips is generally linked to the overall level of economic growth, as analog chips serve as the building blocks of most electronic goods and equipment. Unlike digital chip designers, analog chip makers tend to produce the majority of their own chips, as analog chip production does not require expensive leading edge nodes. Less dependent on major secular growth drivers, analog product cycles are much longer, often 5-7 years.

Power Integrations's revenue growth over the last three years has been solid, averaging 18.5% annually. Last year the quarterly revenue declined from $172.6 million to $124.7 million.

Product Demand & Outstanding Inventory
Days Inventory Outstanding (DIO) are an important metric for chipmakers, as it reflects the capital intensity of the business and the cyclical nature of semiconductor supply and demand. In a tight supply environment, inventories tend to be stable, allowing chipmakers to exert pricing power. Steadily increasing DIO can be a warning sign that demand is weak, and if inventories continue to rise the company may have to downsize production.

This quarter, Power Integrations’s inventory days came in at 215, 75 days above the five year average, suggesting that that inventory has grown to higher levels than what we used to see in the past.
