Convert your design to best performance with Infineon’s integrated power stage and control IC solutions.
Infineon's latest CoolSET™ generation of AC-DC integrated power stages in fixed frequency or quasi-resonant switching scheme offers increased robustness and outstanding performance, enabled by the integration of the latest 700V and 800V CoolMOS™ P7 Superjunction power MOSFET family in both DIP-7 and DSO-12 package. Our integrated power stages in fixed frequency mode convince with higher efficiency performance and lower switching frequency at mid and light load condition enabled by an integrated frequency reduction operation. The quasi-resonant CoolSET™ power stages impress with an intelligent digital algorithm, which allows the PWM controller to minimize the spread of switching frequency under different AC line input conditions.
A wide selection of highly efficient AC-DC PWM-PFC control ICs facilitates our customer to meet new demands such as PFC regulations and ultra-low standby power requirements in a very cost effective manner. Infineon’s offer ranges from different types of resonant mode power supplies to a number of continuous conduction mode PFC controllers. The latter supports wider VCC operating ranges, improved internal oscillator and additional direct bulk capacitor overvoltage protection, which results in high efficiency and very low system cost. Infineon’s LLC resonant mode control ICs achieve a higher level of efficiency at low switching losses. This topology allows the elimination the secondary filter inductor, adopt better rectifier diodes and secondary conduction loss is reduced.
With our offer of integrated AC-DC power stages as well as high power controllers, Infineon solves the formula of how to convert AC to DC the best.
