Switching Converter, SMPS Transformers
Switching Converter and SMPS Transformers are magnetic components used in switching power supplies to transfer energy, provide isolation and support voltage conversion. They are widely used in AC-DC power supplies, DC-DC converters, adapters, chargers, industrial power modules, LED drivers, communication equipment, consumer electronics and embedded systems.
This category includes flyback transformers, forward converter transformers, push-pull transformers, isolated DC-DC converter transformers, high-frequency SMPS transformers and related magnetic components. These products are commonly selected based on input voltage, output voltage, power rating, switching frequency, insulation rating, core material, mounting type, package style and application requirements.
TomatoElec supplies original Switching Converter and SMPS Transformers from recognized manufacturers such as Würth Elektronik, Pulse Electronics, Bourns, TDK, Murata, Coilcraft, Triad Magnetics, Eaton and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
