Infineon Technology provides ac-dc controllers, dc-dc converters, MOSFETs, 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.

With the introduction of gallium nitride, Infineon is currently the only company in the market offering a full-spectrum portfolio of all power technologies – silicon (Si), silicon carbide (SiC) and GaN. We deliver solutions from microamps to megawatts as discrete or integrated solutions—depending on your preference.

AC-DC switch mode power supplies (SMPS)

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.
