Toroidal inductor, DC DC Converter Transformers are used in step-up or step-down converters. These transformers can be used in self-saturated or square wave driven applications. These ultra-miniature transformers are made for durability while maintaining their electrical characteristics. Custom designs are available to increase or decrease secondary voltages as well as any specific input voltages.
