Switched mode power supplies (SMPS)
Please choose a subcategoryCollapse all subcategories Expand all subcategories
In a AC-DC SMPS, the AC is a converter to a defined DC output power. Therefore the AC mains is rectified and filtered and feeds the power factor correction (PFC) stage. Via high-frequency modulation, in a second step, it is then delivered to a DC load with the desired voltage and current.
Infineon Technology provides a full spectrum of power controllers and switches, including ac-dc controllers, dc-dc converters, silicon and SiC MOSFETs, GaN HEMTs, Intelligent Power Modules, lighting ICs, transistors (IGBTs), diodes and rectifier, regulators, isolation interfaces, voltage and current management for internal and external power supply applications.
Our design solutions increase active-mode efficiency, decrease standby-mode power consumption, and provide power factor correction at every stage of your layout from line to load. Depending on your requirements, Infineon delivers solutions from microamps to megawatts as discrete or integrated devices.
