August 18, 2026— The global switch mode power supply transformers market was valued at USD 3.01 billion in 2025 and is projected to reach USD 5.09 billion by 2036, expanding at a 4.9% CAGR from 2026 to 2036, according to Fact.MR. The market is estimated at USD 3.16 billion in 2026 and is expected to create an absolute dollar opportunity of USD 1.93 billion between 2026 and 2036.

SMPS transformers are magnetic components used in power conversion circuits. They provide galvanic isolation, voltage transformation, and energy storage at high switching frequencies. Demand is supported by consumer electronics chargers, data center power supplies, EV onboard chargers, industrial power conversion, and wider adoption of GaN and SiC power semiconductors. Higher switching frequencies allow manufacturers to develop smaller transformer designs with lower copper content.

Segment Breakdown

Ferrite cores lead the core-material segment. Ferrite core transformers are expected to hold 35.6% share in 2026. MnZn and NiZn ferrite grades provide the magnetic performance needed across common SMPS switching frequencies. Ferrite cores also benefit from wide availability and competitive pricing.

Flyback transformers lead the product segment. Flyback transformers account for 28.4% of the product segment in 2026. They are widely used in low- to medium-power applications such as phone chargers and small adapters.

Isolated transformers lead the topology segment. Isolated SMPS transformers hold 39.1% of the topology segment in 2026. They provide galvanic isolation needed in consumer, medical, and industrial power supplies.

Consumer electronics remains the largest application. Consumer electronics power supply is expected to represent 30.2% of the application segment in 2026. Smartphone chargers, laptop adapters, tablets, and wearable-device chargers create large-volume demand.

Planar transformers are emerging as a growth area. GaN-optimized planar transformers use PCB-integrated windings. The page states that, combined with GaN switches operating above 500 kHz, these designs can achieve power densities 2 to 3 times higher than conventional designs.

Country CAGR Outlook
