According to Semiconductor Insight, Switch Mode Power Supply Transformers Market size was valued at USD 1595 million in 2024 to USD 1416 million by 2032, exhibiting a negative CAGR of -1.7% during the forecast period.
Switch Mode Power Supply Transformers (SMPS Transformers) are specialized components used within regulated power supplies to step up or step down voltage or current, and to provide galvanic isolation between the input and output sides of a switch mode power supply. These transformers operate by varying the duty cycle of the input voltage waveform on the primary side to deliver a constant output voltage across varying load conditions. They are engineered to function efficiently at high frequencies, typically ranging from 10 kHz to 1 MHz, and can handle power levels extending up to 50 kilowatts.
The market is experiencing a slight contraction, primarily due to increasing miniaturization and integration of power electronics, which reduces the volume of transformers required per unit. However, this is counterbalanced by sustained demand from key end-use industries. The Asia-Pacific region dominates the market, holding approximately 75% of the global share, driven by its massive consumer electronics manufacturing base. The single-excited transformer type is the largest product segment, accounting for over 65% of the market, while consumer electronics remains the leading application. Key players such as TDK, Tamura, and Sumida
