A Switching Converter, also known as Switched-Mode Power Supply (SMPS) Transformer, is an electronic component critical to regulating and optimizing the power supply to electronic devices. These dynamic components convert electrical power efficiently from one form to another, using switching techniques and storage components to influence the voltage, current, and frequency. They are broadly utilized for their high efficiency, enhanced power density, and reconfigurable nature. The SMPS transformers are compact in size and can operate across a wide range of input voltages, making them an essential part of various electronic and electrical systems.

With their efficient power regulation capabilities, SMPS transformers find their usage in many applications such as laptop chargers, LCD monitors, telecommunication equipment, and in the automobile industry. They are known for their high electrical efficiency, low heat dissipation, and ability to work on varying power sources, making energy consumption more efficient and safe. Some of the key manufacturers in this sector include Infineon Technologies, Texas Instruments, Murata Manufacturing, and Pulse Electronics.
